8790 HMB Deep Long Socket Wrench with 3/8" Drive, 10 x 64 mm (8790HMBDeep)

3840/1 TS Hex Keys, Stainless Steel

Hex-Plus

Internal hex screws are problematic because the bearing surfaces through which the tool's force is transmitted to the screw are extremely narrow. This can damage the screw head. Hex-Plus tools have larger bearing surfaces that prevent this type of damage. And it's worth remembering: Hex-Plus tools fit any standard hex screw!

Stainless steel tips

Using stainless steel tips prevents rust from forming on stainless steel screws or surfaces. Contamination on stainless steel primarily results from abrasion when tightening screws with conventional steel tools. Abrasion produces strongly adherent steel particles that, under the effect of oxygen, turn into rust.

Screw stainless steel to stainless steel!

The solution to the contamination problem: Screw stainless steel with stainless steel! Wera stainless steel tools are truly made of 100% stainless steel, preventing unsightly contamination.

Cold and vacuum hardening treatment

Wera's stainless steel tools undergo cold and vacuum hardening, providing the necessary hardness and strength for screwdriving applications. This allows for unrestricted industrial use.

Item description

High-quality stainless steel bits for internal hex screws. Wera stainless steel tools are made of stainless steel, thus preventing the formation of unsightly rust from external sources. The Hex-Plus profile provides larger contact surfaces within the screw head. This minimizes the scoring effect and virtually eliminates damage to the screw head. Torsion zone: In the case of torsion bits, torque peaks are dampened within the torsion zone. This prevents premature wear and increases the bit's lifespan. 1/4" hex shank, suitable for bit holders according to DIN ISO 1173-D 6.3.
