The best chemical anchors, compared.
Top pick: Rawlplug R-KEM-II 300 ml – Styrene-free 300 ml cartridge the listing says fits a standard gun, 4.5 from 134 ratings, for crack-free concrete, with the kit-contents clash as the limit. Best value: fischer FIS P Plus (Tubo 290) – Lowest price in the set at about £11.28, with 312 ratings, for masonry or non-cracked concrete if your gun already fits this cartridge. Updated October 2026.
A chemical anchor is a two-part resin that bonds a threaded rod or socket into a drilled hole, instead of expanding like a shield anchor. In the UK you buy one when a plastic plug or an expanding bolt is the wrong method for masonry or concrete, such as a gate bracket in solid brick or a stud that must sit in a sized hole. You recognise a suitable pack by the stated base, the chemistry, the cartridge shape, and what is actually in the box. The listing should name solid masonry, non-cracked concrete, cracked concrete, or hollow brick that needs a sleeve. A standard silicone gun is a match only when the page says so. A coaxial tube needs the dispenser that drives it. Styrene-free wording is the indoor cue. When failure could hurt someone, BS 8539 and an ETA or UKTA you can quote take over from a shopping comparison. Out-of-date resin is rejected, not tried on a handrail. The order of those checks, before price, is the [chemical anchor buying guide](/hub/screws-and-accessories/chemical-anchor/sub/chemical-anchor-buying-guide).

Question 1 of 2
What does the base need?
The Rawlplug R-KEM-II-300 is a 300 ml styrene-free polyester cartridge at £12.10, with 4.5 stars from 134 amazon.co.uk ratings, the highest star line in this set. The listing says it fits a standard manual or silicone dispenser and describes the resin as odourless for interior use on crack-free concrete, with stone only after you test it. You can plan the job around a gun most people already own, which is why it leads on stated kit rather than on price. The title calls it a fixing kit with threaded rods and two mixers, yet UK reviews say the parcel was resin only and that nozzles arrived missing or cracked. Treat the box as a cartridge until you open it, and buy rods separately. Once mixing starts, the working time is still short, so the hole and the rod need to be ready before the first trigger. It is the top pick here for a styrene-free 300 ml cartridge on crack-free concrete when a normal gun is the point, with that kit-contents clash as the limit.
Pros
Cons
Best for: Crack-free concrete where you want a styrene-free 300 ml cartridge that the listing says fits a standard silicone gun.
Less suitable: Anyone treating the title as a stud kit, or a specification that needs cracked concrete.
Specifications
Common questions
Are threaded rods in the box?
The title says a fixing kit with threaded rods. UK reviews say the parcel was resin only.
Will it fit a standard silicone gun?
The listing says it can be used with standard manual and silicone dispensers.
Does the listing say it is styrene free?
Yes. The title says styrene free and the bullets describe it as odourless for interior use.
fischer FIS P Plus on the Tubo 290 listing is £11.28, the lowest price here, with 4.4 stars from 312 amazon.co.uk ratings, the largest sample in the set. You get one polyester hybrid cartridge and one MR mixer, model 567059 and part 523226, and a dispenser is not in the included-components line. The listing describes masonry and non-cracked concrete, and it names threaded rods, internal threaded anchors, and anchor sleeves as the system. Reviewers report missing nozzles, a short working time, and resin that stays sandy part-way down the tube, so a spare mixer matters more than the star line suggests. A 3,050 kg figure sitting beside tyre fields is not a verified holding load. It is the best value when the job matches non-cracked concrete or masonry and you already own a gun that accepts this cartridge, which the page does not confirm. Leave it when the drawing asks for cracked concrete.
Pros
Cons
Best for: A polyester hybrid cartridge for masonry or non-cracked concrete when you already have a suitable gun.
Less suitable: A cracked-concrete specification, or a buyer who needs the gun in the box.
Specifications
Common questions
Does this cartridge include a dispenser?
The listing includes one cartridge and one MR mixer. A dispenser gun is not in the included-components line.
Which bases does the listing name?
The listing describes masonry and non-cracked concrete, for threaded rods, internal threaded anchors, and anchor sleeves.
Is 3,050 kg a tested holding force?
That figure sits in the same Amazon attribute block as tyre fields such as tread type. It is not treated as a verified anchor load.
Bond It Anchor Bond is £13.19 with 4.3 stars from 109 amazon.co.uk ratings, and a bullet says no special gun is required. The listing calls it polyester resin for solid and hollow bases, water resistant, with a full-cure attribute of 2 hours. Volume is printed twice and the figures do not agree: item volume 300 ml, unit count 310.01 ml, model BDAB380, part BDAB310. Reviews report a missing nozzle and a very short working time, and the listing does not state a mixer. Styrene-free is absent from the raw page, and cracked concrete is not named. On a hollow base the bullets still give no sleeve part number, so the cartridge alone does not finish that method. It suits a grey resin the listing says runs in a normal gun, and it is a weak match when you need styrene-free wording or a cracked-concrete line on the page.
Pros
Cons
Best for: A grey cartridge the listing says works with a normal gun on solid or hollow bases.
Less suitable: A buyer who needs styrene-free wording, a cracked-concrete claim, or a named sleeve.
Specifications
Common questions
Does the listing say a special gun is required?
No. A bullet says no special gun is required.
What volume is printed?
The item volume is 300 millilitres and the unit count is 310.01 millilitres. The model is BDAB380 and the part number is BDAB310.
Is styrene-free stated on this listing?
No. The raw listing does not say styrene-free. Bond It's BDAB310 sheet says that resin contains styrene.
The fischer FIS P Plus 380 C is a 380 ml polyester hybrid at £13.29, with 4.2 stars from 38 amazon.co.uk ratings and one MR mixer stated, model 522178. Bullets name masonry and concrete, indoors and outdoors, plus FIS A rods, FIS E internal threads, and anchor sleeves. UK reviews say a normal sealant gun will not drive it and describe a specialist gun with a ring-shaped drive. The larger fill only helps if that gun is already yours. Rods are not in the box, cracked concrete is not stated, and styrene-free is not stated. Thirty-eight ratings is a thinner sample than the Tubo 290 listing of the same mortar family. Choose it when the coaxial gun is on the bench, and leave it if your only dispenser is a standard silicone gun.
Pros
Cons
Best for: Someone who already has the coaxial gun this 380 C needs.
Less suitable: A standard silicone gun already in the drawer, or a cracked-concrete specification.
Specifications
Common questions
Will this fit a normal sealant gun?
UK reviews say it does not. They describe a cartridge that needs a specialist gun with a ring-shaped drive.
What is in the box?
The listing says one cartridge and one MR mixer. Rods are not listed.
Which bases does the listing name?
Bullets say masonry and concrete, indoors and outdoors, and name FIS A rods, FIS E internal threads, and anchor sleeves as the system.
fischer RM II 12 is a pack of ten resin capsules, part 539798, at £12.62 with 4.0 stars from 10 amazon.co.uk ratings. The bullets describe fixings in cracked concrete, including overhead and single applications, and they say processing is fast without drill-hole cleaning. Included components are the capsules only, so the matching rod is a separate purchase, and this is not a cartridge with a mixer. A UK review calls the capsules brittle, which matters if the glass is chipped before you set the rod. The pack does not name anchor sleeves, so it is the wrong format for perforated brick. Ten ratings is a small sample next to the cartridge rows. It fits a few cracked-concrete points when you already hold the correct rod, and it does not replace an injection cartridge.
Pros
Cons
Best for: A few capsule fixings in cracked concrete if you already have the matching rod.
Less suitable: Hollow brick, or anyone who needs a cartridge and a mixer.
Specifications
Common questions
Are the anchor rods included?
No. Included components are 10 resin capsules.
What base does the listing name?
The bullets say fixings in cracked concrete, including overhead and single applications.
Does the listing say to clean the hole?
A bullet says fast processing without drill hole cleaning. fischer pairs this capsule with a 14 mm hole and 110 mm embedment, and only with the matching rod.
Metalmate’s styrene-free polyester cartridge is the largest fill here at 410 ml, listed at £14.13 with 4.0 stars from only five amazon.co.uk ratings, model 0868EA410. The title and bullets say styrene free, including for indoors and enclosed spaces, and they claim an ETA for concrete and masonry or hollow wall. No ETA number is printed in the capture, so you cannot check the approval from this page. The only UK review in the raw says the application straw was not in the parcel, and a mixer is not stated. A standard silicone gun is not stated either, and rods are not included. Five ratings cannot carry a specification. It can cover a non-critical job where you already accept the missing approval number, and it is a poor fit when the paperwork needs an ETA you can quote.
Pros
Cons
Best for: A 410 ml styrene-free cartridge for a non-critical job where a printed ETA number is not required.
Less suitable: A specification that needs an ETA number you can quote before you buy.
Specifications
Common questions
Does the listing name an ETA number?
It says ETA approval for concrete and masonry or hollow wall. No ETA number is printed in the capture.
Is it styrene free on the listing?
Yes. The title and bullets say styrene free, including for indoors and enclosed spaces.
Did the review mention a nozzle?
The only UK review in the raw says the application straw was not in the parcel.
The listing titled FIS VL 300 T is £20.49, the highest price in this set, and the raw capture has no Customer Reviews line. Brand and manufacturer fields say sarcia.eu, while the model number is 540983 and the title uses the Fischer FIS VL 300 T name. You should not treat the brand row as a confirmed fischer article. Bullets describe a 300 ml vinyl ester cartridge for a standard silicone gun, and they name cracked concrete plus solid and hollow masonry. A mixer is not stated, and rods are not stated. Without reviews you only have the listing text, which is a real gap at this price. Open it only after you have checked that 540983 is the vinyl ester you were specified, and skip it if you need review evidence or a brand field that says fischer.
Pros
Cons
Best for: A reader who has checked that model 540983 is the vinyl ester cartridge they were specified.
Less suitable: Anyone who needs review evidence or a brand field that says fischer.
Specifications
Common questions
Who is the brand on the listing?
The brand and manufacturer fields say sarcia.eu. The model number is 540983. The title uses the Fischer FIS VL 300 T name. This page does not treat it as fischer article 539461.
Is there a star rating?
No Customer Reviews line is in the raw capture.
What gun does the listing mention?
The bullets say the 300 ml cartridge is for standard silicone guns.
Seven amazon.co.uk listings were scored from the stored pages dated 20 October 2026. There is no pull-out test and no laboratory ranking. Stars are the listing line. No review line scores 0 on the star part. The top pick is the Rawlplug R-KEM-II 300 ml. The best value is the fischer FIS P Plus Tubo 290. The weights below sum to 100. Deductions, already applied in the scores, cover a title that disagrees with reviews, a missing nozzle or rod, an ETA claim with no number, and a brand field that does not match the title.
Amazon stars
40%amazon.co.uk stars divided by 5, then times 40. A listing with no Customer Reviews line scores 0 on this part.
Review depth
20%Up to 20 points for the number of amazon.co.uk ratings: 20 at 300 or more, 16 at 100 or more, 8 at 30 or more, 5 at 10, 3 at 5, and 0 if none.
Stated kit and substrate
25%Up to 25 points for the chemistry, the base the listing names, whether a mixer is stated, and whether a standard gun is actually stated.
Price position
15%Up to 15 points. A lower shelf price in this set of seven scores higher. Price does not override a cracked-concrete specification.
Choose the wall, the chemistry and the cartridge shape before the price. A star line does not tell you whether the tube fits the gun you own, or whether the rod is in the box. Epoxy is not in this set of seven listings.
A chemical anchor is a two-part resin that bonds a threaded rod or socket into a drilled hole. It does not expand like a shield anchor. On amazon.co.uk the choice is a polyester cartridge for masonry and non-cracked concrete, a styrene-free polyester when you want lower odour indoors, a vinyl ester where the maker states cracked concrete, or a pre-portioned capsule for a few holes in concrete. Quality is the match between the resin, the steel, the wall, and the install sequence.
UK reviews of the FIS P Plus 380 C say a normal sealant gun will not drive it. fischer says the FIS P Plus 300 T works in a standard silicone dispenser. The Tubo 290 listing does not state that gun. Buy the tube that matches the gun you own.
The Rawlplug title says a fixing kit with threaded rods and two mixers. UK reviews say the parcel was resin only, and that a nozzle arrived missing or cracked. The RM II pack is ten capsules and does not include the rod.
Injection holes on the Rawlplug and Ceresit sequences are brushed and blown, the first squeezes are discarded until the colour is even, and the stud waits for the cure time at that base temperature. Perforated brick needs a sleeve. The RM II capsule is the stated exception: no hole cleaning, and only with the matching rod in concrete.
Start with the wall. fischer describes FIS P Plus as a polyester hybrid for masonry and non-cracked concrete from C20/25 to C50/60, citing ETA-18/0383 and ETA-11/0419. ETA-11/0419 records no seismic performance and no fire resistance under load for that masonry system. Rawlplug describes R-KEM II as styrene-free polyester for non-cracked concrete, with ETA-21/0243 and UKTA-22/6131 on its concrete datasheet, and stone only after you test it.
The gun and the parcel decide whether the resin you chose can be installed. fischer says the FIS P Plus 300 T works in a standard silicone dispenser. UK reviews of the 380 C, at about £13.29, say a normal sealant gun does not drive that coaxial cartridge. Rawlplug and Bond It both state a normal gun on the listing. The Tubo 290 page does not. Mixers go missing in reviews, so a spare nozzle matters more than the star line.
Three typical situations, each with a recommendation from this comparison.
You need a cartridge the listing says fits a standard gun, and a hole you will brush and blow. The Rawlplug R-KEM-II 300 ml is about £12.10, styrene-free on the listing, with 4.5 from 134 ratings. UK reviews say the rods in the title were not in the parcel.
You want a resin the maker calls styrene-free, and you still wear eye protection and gloves. The same Rawlplug listing describes the resin as odourless for interior use on crack-free concrete. It is not a cracked-concrete system.
If someone could be hurt if the fixing failed, follow BS 8539 and the ETA or UKTA, not the star line. In this set the cracked-concrete capsule is the fischer RM II 12 pack of ten, about £12.62. The rod is not included, and there are 10 ratings.
The top pick is the Rawlplug R-KEM-II 300 ml at about £12.10. The listing says styrene-free polyester for a standard silicone gun, odourless for interior use on crack-free concrete, with 4.5 from 134 amazon.co.uk ratings. The title says threaded rods and two mixers; UK reviews say the parcel was resin only. The best value is the fischer FIS P Plus Tubo 290 at about £11.28, with 4.4 from 312 ratings, for masonry or non-cracked concrete when you already have a gun that accepts that cartridge. Neither is a cracked-concrete system. None of these scores is a pull-out test.
