STANLEY STHT0-51310 Curve-Claw Fiberglass Hammer, 560 g

STANLEY STHT0-51310 Curve-Claw Hammer, 560 g head

The STANLEY STHT0-51310 is a framing hammer with a curved claw and a 560 g (20 oz) head on a fibreglass-core handle. The manufacturer classifies it among framing hammers and specifies a longer handle for more force at the same effort.

High-carbon steel head

The head is forged from high-carbon steel. The striking face is smooth and round, with a tempered rim - the rim of the face is exactly where hammers most often chip on an off-square blow, which is why it is heat treated.

Fibreglass-core handle

The core is fibreglass, which gives strength at lower weight and absorbs part of the vibration instead of the wrist doing so. The joint between head and handle is reinforced with a two-component epoxy adhesive. Handle length is 319.4 mm.

Ergonomic grip

The grip is bi-material, with a ribbed surface and a flared end that stops the hand sliding off on a hard swing. The balance is set so the head's momentum does the work and the wrist tires more slowly over a long day.

Curved claw

The curved claw gives a longer lever arm when drawing nails - the back of the head bears on the board and the nail comes out with less effort. It is the classic shape for framing and carpentry work.

Dimensions and standard

Overall length is 325 mm, width 135 mm, and the weight of the complete tool is 0.785 kg. The manufacturer states conformity with ASME B107.400. The same model is also offered in a 16 oz version.
