Bosch Claw Hammer 1600A03AK6, 20 oz / 567 g

The Bosch 1600A03AK6 is a curved claw hammer with a carbon steel head weighing 0.57 kg (the head itself is marked 20 oz / 567 g) and an overall length of 333 mm. The complete tool weighs 0.836 kg and the head hardness is HRC 50-58. The tool is built to the ISO 15601 standard.

Fibreglass-cored handle

The handle has a fibreglass core - a material with a 65% fibreglass ratio according to the manufacturer. Fibreglass absorbs much of the vibration that a wooden or one-piece steel handle sends back into the wrist, and it does not shrink and loosen the way wood does. Over it sits a multi-component grip that holds in a sweaty or oily hand. At the end there is a tether hole - on scaffolding or a roof the hammer is clipped on and will not fall.

The head

The striking face is large, and that is safety rather than styling: more area means less chance of catching the edge of the face and sending the nail sideways. The other side carries the V-shaped claw with a curved profile. The curve is the geometry that turns the swing into a lever: once the claw has taken the nail head, rolling the hammer draws the nail out instead of bending it. A hardness of HRC 50-58 is the range in which the face does not dent and the claw does not snap under load.

Applications

Driving and pulling nails in formwork, scaffolding, timber framing, sheathing and stripping out. Twenty ounces is the most commonly preferred weight for everyday carpentry - enough for a 90 mm nail in a few blows, but not so heavy that the arm tires within the hour.
