Claw hammer buying guide: job, then ounces, then the handle

Updated: 23 October 2026

You are on amazon.co.uk with a dozen claw hammers, a photo that makes an 8 oz head look full size, and a sort that rewards review count. The hammer you need depends on the nails you drive this year: picture hooks, a fence board, or longer nails into softwood studs. By the end you should know which head weight to search for, and which details can wait. Peter F. checked the twelve listings in the [hammer comparison](/hub/hand-tools/hammer) on 22 October 2026. Prices are those shelf figures in GBP. We did not swing these hammers in a lab. A qualifying purchase through our links can earn a commission at no extra cost to you.

Start with the job, not the photo

A claw hammer drives unhardened nails into timber and pulls them out. The job decides the head. Picture hooks, panel pins and tent pegs are an 8 oz task, about 225 g in the head. Flat-pack, skirting, a door and the odd fence board are the 16 oz task UK trade guides treat as the homeowner default. Longer nails into framing timber are where a 20 oz head earns its keep. Name the job, then open the 16 oz or 20 oz claw hammer page.

Read the ounces as the head

The ounce figure names the head, so a 16 oz hammer can weigh more than 450 g and still be honest. Stanley's FMHT1-51275 sheet lists a 453 g head and a product weight of 0.697 kg. Amazon's item-weight row for that FatMax is 697 g. Rolson 10339 is titled 16 oz with an item weight of 454 g. The Estwing E16C title says 450 g (16 oz) and the item weight is 454 g. The Roughneck title says 20 oz / 567 g, code 11-010 matches, and the amazon row prints 82 g. That row is not the hammer. Believe the title and the maker table when the rows disagree.

Claw and handle are the next two choices

A curved claw gives more leverage when you pull a nail. A straight claw, often called a rip claw, is the shape for prying and splitting boards. Most household jobs are pulls, and neither shape is a wrecking bar. The Amtech listing says straight in the title and curved-claw leverage in a bullet, so check the photograph on the curved or straight claw page. Hickory absorbs the most shock and can loosen. Fibreglass sits between hickory and steel. One-piece forged steel has no wedge to loosen. The FatMax bullets say that. The Estwing bullets do not, though reviewers describe the E16C that way.

What the price in this set is buying

Shelf prices run from about £4.99 to about £37.00. Rolson 10334 is about £7.56 with 4.6 from 2,791 reviews and it is an 8 oz hammer, so review count puts a pin hammer first. Rolson 10339 is the 16 oz tubular at about £7.99 with 4.6 from 881 reviews. UK reviews on lighter two-piece hammers describe snapped claws on a long nail. The Roughneck is about £20, 4.7 from 311 reviews. The FatMax is about £27.95, and one UK review says the claimed magnet was missing. The Estwing is about £37, leather grip, origin row USA. None of the twelve files says BS 876. One listing per job is best claw hammer UK.

Common questions

What weight claw hammer do I need for ordinary DIY?
For doors, skirting, flat-pack and the odd fence board, a 16 oz head is the default BuildWiz UK describes, about 450 g in the head. In this set that title appears on the Rolson 10339 at about £7.99, the Stanley FatMax at about £27.95 and the Estwing E16C at about £37.00. An 8 oz hammer is for pins. A 20 oz hammer is for longer nails you drive often. The ounce is the head, so check the title before you trust the photo.
Is an 8 oz hammer enough for fence nails?
An 8 oz head will start panel pins and picture hooks. Fence nails and long pulls are where reviews on the Amtech, the Rolson 10334 and the Arcjunys describe bending, a snapped claw tooth or a head that left the handle. If the fence board is the job, move to a titled 16 oz hammer and put a scrap of timber under the head when you pull. The small hammer can stay in the drawer for pins.
Does a high review count mean a better hammer?
Rolson 10334 has the largest count here, 4.6 from 2,791 reviews, at about £7.56, and the title is 8 oz. The count reflects an old listing and a lot of light household use. It does not vote for framing. The Estwing has fewer reviews, 749, at a higher price, and the reviews talk about keeping the hammer. Read the head weight in the same glance as the stars.
Fibreglass, wood or steel handle?
Hickory absorbs more shock and can loosen as it dries. Fibreglass is the middle option and is what the Bargain Hound set uses. Solid steel, including one-piece forgings, keeps the head on by removing the wedge joint and sends more of the blow into your hand. Stanley's tuning fork and Roughneck's V-Shock are claims. Choose steel when the head coming off is your worry, and a damped handle when the session is long.
What is BS 876 and does this listing meet it?
BS 876:1995 is the British specification for hand hammers, including claw hammers. BSI lists it as current and under review. It applies when a contract asks for it. None of these twelve amazon.co.uk files says BS 876. We did not test them against it. ASME B107.400 on Stanley's sheet is a US maker citation, not a UKCA mark.
