Precise fastening with Wera
- Prevents rounded screw heads: The specialized Hex-Plus design creates larger contact surfaces so you avoid damaging and stripping socket head screws.
- Tough against heavy loads: Engineered with tough-absorbing steel, this bit absorbs torque peaks to prevent you from experiencing premature tip breakage.
- Universal bit holder fit: Featuring a standard 1/4" hexagon drive and 50 mm length, you achieve a secure fit in your holders and drivers.
Drive socket head screws with complete confidence and protect your fasteners from damage. With the Wera 840/4 z Hex-Plus hex bit measuring 4 x 50 mm, you tackle machinery maintenance, vehicle repairs, and furniture assembly with ease. The innovative Hex-Plus profile delivers a larger contact surface inside the screw head, effectively preventing stripped and rounded recesses. Made from tough-absorbing steel, this bit withstands heavy torque peaks to prevent premature tip breakage during demanding fastening tasks. Its extended 50 mm length gives you easy access to recessed screws, while the standard 1/4" hexagon drive according to din iso 1173-F 6.3 guarantees a secure fit in your bit holder for optimal power transfer.

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.
