Wera Tools 3840/1 TS 2.5/25 Hex Bit

• Hex-Plus allows socket head screws to live longer

For socket head screws

Solution to the extraneous rust problem: fasten stainless screws with stainless tools

High-quality bits of stainless steel for hexagon socket screws.

The Hex-Plus profile offers a greater contact surface in the head of the screw. The notching effect is therefore reduced to a minimum and damage to the screw head more or less eliminated.

Torsion bits take up torque peaks and absorb them in the Torsion zone. This prevents premature wear and extends the service life of the bit. 1/4" hexagon, suitable for holders as per DIN ISO 1173-D 6.3.
