Reliable screwdriving with Wera
- Prevents screw head damage: The specialized contact geometry gives you larger contact surfaces to prevent rounded hexagonal screw heads.
- Tough absorbing core design: You withstand high torque peaks during demanding fastening jobs thanks to the ductile, break-resistant construction.
- Standard universal drive fit: Easily secure this 25 mm bit into any standard 1/4" bit holder or power driver chuck.
Fasten hexagon socket screws with confidence using the Wera 840/1 z Hex-Plus 4 x 25 mm bit. Featuring the specialized Hex-Plus geometry, this bit provides larger contact surfaces in the screw head to effectively prevent rounding out and stripping the recess. The tough-absorbing z design handles high torque peaks with ease, minimizing the risk of premature tip breakage during demanding fastening tasks. Fitted with a standard 1/4" hexagon drive, this 25 mm bit fits directly into any common bit holder or cordless screwdriver, making it a reliable solution for bicycle maintenance, furniture assembly, and workshop repairs.

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.
