840/1 Z Tamper-proof BO Hex Tips

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!

Extra-tough tips

Wera's extra-tough (Z) tips prevent premature breakage of the tip end. Z tips are typically the most suitable tips for universal applications.

For internal hex screws with a central locking pin (BO = with hole)

Hex-Plus makes internal hex screws last longer

Durable and sturdy, for universal use

Item description

Wera's durable and robust internal hex head bits are designed for universal applications. The Hex-Plus profile provides larger contact surfaces on the screw head, minimizing the stripping effect and virtually eliminating damage to the screw head. The drive profile of BO internal hex head screws features a prominent pivot point, preventing unexpected loosening, as these screws cannot be worked with standard hex tools. The 1/4" hex shank is compatible with bit holders according to DIN ISO 1173-D 6.3.
