Wera 05056682001 Hex-Plus 2.5 mm Hexagon Screwdriver Bit, 25 mm, 1/4 inch Drive

When a technician reaches for a bit to drive a 2.5 mm hex socket screw in a precision assembly, the Wera 05056682001 delivers a secure, non-slip fit. The Hex-Plus profile grips the screw head on the flats rather than the corners, preventing rounding and extending screw life. This 25 mm bit is made from high-alloy steel with a zinc phosphate finish for corrosion resistance, and its 1/4" hex shank fits all standard bit holders and quick-release chucks.

Key specifications

• Bit tip type: Hexagon (Hex-Plus profile)
• Tip size: 2.5 mm
• Overall length: 25 mm
• Drive: 1/4" hex shank
• Material: High-alloy steel with zinc phosphate finish
• Series: 840/1 Z (tough-absorbing for universal use)

Why choose it

The Hex-Plus geometry is the standout feature: it contacts the screw head on the flat surfaces, not the corners, which dramatically reduces the risk of rounding out the socket. Combined with the tough-absorbing Z-series design, this bit withstands high torque and repetitive use in industrial environments. The zinc phosphate coating provides a durable, non-reflective finish that resists corrosion.

Ideal use cases

• Assembly and maintenance of precision equipment with 2.5 mm hex socket screws
• Automotive interior and electronic component work
• Furniture assembly and machine building
• Use with cordless screwdrivers, drills, or hand drivers in 1/4" bit holders

Good to know

This is a single bit, not a set. It is not magnetic and not impact rated, so it is best suited for standard screwdriving applications rather than impact drivers. The bit is compatible with Wera's Rapidaptor holders and any standard 1/4" hex bit holder. For optimal performance, pair with a Wera bit holder to ensure a secure lock and quick bit changes.
