Precision fastening without slipping

Practical benefits

Optimized Wera profile: The geometry expands the contact surface inside the screw head to prevent rounding out and extend fastener service life.
Tough viscous steel: The shock-absorbing structure dampens torque peaks effectively so you prevent premature tip breakage during demanding fastening tasks.
Universal tool fit: Featuring a standard 1/4" hexagon drive and 50 mm length, you easily insert this bit into conventional bit holders.

In a nutshell

The right choise for

With the Wera 840/4 z Hex-Plus hexagon bit, you achieve precise, damage-free fastening on all 2.5 mm socket head screws. The specialized Hex-Plus profile creates larger contact surfaces inside the screw head, significantly reducing notch effect and preventing fasteners from rounding out. Engineered from tough viscous steel, the bit effectively absorbs torque peaks to prevent premature tip breakage during demanding fastening into hard materials. With a total length of 50 mm, you gain extra reach for recessed screws in tight mechanical spaces. The standard 1/4" hexagon drive fits smoothly into conventional bit holders and power tools.

Design

Hex-Plus, tough, for universal use

Features and benefits

Hexagon socket screws are a problem, because the contact surfaces that transfer the force of the tool to the screw are very narrow. The consequence: the head of the screw can be damaged, usually rounding out the recess. Hex-Plus tools have larger contact surfaces to prevent this, driving from the flats of the recess, rather than the corners. Good to know: Hex-Plus tools fit into every standard hexagon socket screw!
Tough Wera bits prevent the tip from breaking prematurely. Z-bits usually are the bit for universal screwdriving applications.
