Claw hammer buying guide

Updated: 22 October 2026

You are on amazon.co.uk with titles that all say claw hammer, while the ounce and the gram row often describe different masses. This claw hammer buying guide is the order of checks before the stars: the job, whether the title and the item-weight row agree, then the claw and the handle. Peter F. updated this on 22 October 2026 from twelve amazon.co.uk listings snapshotted on 19 October 2026. It is not a lab test. A qualifying purchase can earn us a commission at no extra cost to you. Prices stay on the [Claw hammer comparison](/hub/hand-tools/claw-hammer).

What you are actually buying

A claw hammer drives a nail with its face and pulls it with a forked claw. A club hammer is the short head you pair with a bolster or a cold chisel. Toolstation’s guide separates those jobs, then handle material, then head weight, and it tells you to wear eye protection. If the next strike is for masonry or a chisel, put the claw hammer down. Judge the nail, not the word framing. An 8 oz hammer suits panel pins and a light bag. UK guides treat about 16 oz as the controllable weight for doors and skirtings, and about 20 oz as the extra blow for larger softwood nails. The star rating comes after the numbers agree, not before.

Head weight, and when the gram row disagrees

Treat 16 oz as about 454 g and 20 oz as about 567 g. That is a rule of thumb for a head, not a weight we scaled on these ASINs. If the ounces and the item-weight row sit in different size classes, write both down. The WORKPRO pair is titled 16 oz/720 g, and the item weight is 720 g. Sixteen ounces is not 720 g. The HOUSERAN titles 500 g (16 oz) and the item weight is 500 g, but one bullet says 8 oz. The Uadme says 13 oz in a bullet against an item weight of 670 g. The Arcjunys states no ounces. At 360 g and about 27 cm it is closer to 11 oz than to 16 oz.

Handle, grip claims, and what is not insulation

Look at the joint before the grip word. Fibreglass, hickory, steel, and plastic all appear. BuildWiz treats fibreglass as a reasonable homeowner default because it takes some sting out of a miss. No listing here states a voltage, an insulated-tool standard, or a vibration figure. The WORKPRO bullets say carbon structural steel, and the head-material row says Fiberglass. A further bullet calls the grip non-conductive and gives no voltage. The OX Pro describes a TPR grip on American hickory. Three of six UK reviews in that file describe a cracked or snapped shaft. The forged-head line does not cover the wood.

Standards and the checks that are absent

BS 876:1995 is the British Standard for specified hand hammers, including some claw hammers, with pull-apart, bending, and nail-extraction tests. None of these twelve listings claim it. A star line is not that standard. PUWER 1998 applies when a hammer is work equipment: suitable, maintained, and used by instructed people. A household picture hook sits outside that employer duty. Sealey’s instructions and Toolstation’s guide both put eye protection on the job, because a nail head can fly. A loose head, a split shaft, or a chipped claw comes out of use.

Which check to make before you pay

Buy the hammer whose title and item-weight row describe the same mass, and treat framing as an adjective until those figures agree. A two-pack counts as two hammers only when both are in the box. One Bargain Hound reviewer received only the larger hammer of a titled 16 oz and 8 oz pair. Check the contents before you treat the pair price as two tools.

Common questions

Does fibreglass mean I can use it near live cables?
No. Fibreglass in a retailer guide is about how the handle feels when you miss. No listing here states a voltage or an insulated-tool standard. WORKPRO’s non-conductive bullet gives no voltage, and that page’s head-material row says Fiberglass while the bullets say steel. Keep mains work away from all of these hammers.
What is BS 876 and does any hammer here claim it?
BS 876:1995 specifies certain hand hammers, including some claw hammers, with pull-apart, bending, and nail-extraction tests named in the public record. We have not pasted the standard. None of the twelve listings claim BS 876. Do not infer it from a forged-head bullet, a star rating, or a browse rank.
Is a two-pack two hammers or one hammer with a spare handle?
These packs are sold as hammers, not as a head plus a spare shaft. WORKPRO pairs a 16 oz-class title with an 8 oz title. Bargain Hound is titled 16 oz and 8 oz. Count the pieces you can hold. One reviewer of that pair received only the larger hammer, so check the box before you treat the price as two tools.
When is a claw hammer the wrong tool and a club hammer the right one?
Use a club hammer with a bolster, a cold chisel, or masonry. Sealey limits a claw hammer to nails and light prising, not to every striking job. If the task is demolition or brick, the claw is the wrong shape. Eye protection still applies with the tool you switch to.
Why do reviews say a hammer is tiny when the title says framing?
Framing here is not a measured 20 oz. Fadayunn says framing and also 11 oz, 27 cm, and 330 g, and reviews call it light and better for tacks. ZOFUN’s title says 17 oz and 33 cm, a bullet says up to 20 oz, and one of three UK reviews calls them smaller than a normal claw hammer. Believe the length and the gram row.
