Screwdriver bit Wera 05056305001 — Hex 2 mm, length 25 mm, 1/4" hex shank

Wera 05056305001 is a single screwdriver bit with a 2 mm metric Hex tip and a length of 25 mm, fitted on a 1/4" hexagonal shank compatible with standard bit holders and drivers. The bit is manufactured for use with hexagon socket screws and engineered to provide precise engagement in compact or confined fastening locations. Hex-Plus geometry increases the contact surface inside the screw head to minimise notching and reduce damage during tightening and loosening.

Advantages

The bit combines ductile, tough material properties with accurate tip geometry to deliver reliable torque transfer and extended screw life when used with metric hex fasteners. Its 1/4" hex shank fits common holders that conform to DIN ISO 1173-D 6.3, enabling use with many hand drivers and power tool adaptors. The Hex-Plus design reduces cam-out and wear on the screw head compared with conventional hex bits.

Suitable for

• Maintenance and repair of equipment with metric hex socket screws
• Assembly tasks requiring compact access to recessed hex fasteners
• Precision fastening in electronics, mechanical assemblies and furniture
• Use with standard 1/4" bit holders and quick-change chucks

Key specifications

• Tip type: Metric Hex (2 mm)
• Working length: 25 mm
• Shank: 1/4" hexagonal
• Geometry: Hex-Plus for increased contact surface
• Material properties: tough, ductile bit steel suitable for demanding use
• Compatibility: fits holders and drivers matching DIN ISO 1173-D 6.3

How to use

Insert the 1/4" hex shank into a compatible bit holder, driver or quick-change chuck until it seats securely. Select the 2 mm metric hex bit for the corresponding hex socket fastener and apply steady torque while maintaining axial alignment to avoid slipping. For power tools, set an appropriate torque or speed to prevent over-tightening; for hand use, ensure the driver or handle provides stable support. Replace the bit if signs of tip deformation or wear appear to preserve screw integrity.

Usage recommendations

Use the Wera Hex-Plus bit for applications where preserving the screw head is important. Match the 2 mm tip precisely to the fastener, avoid excessive side load, and choose appropriate torque settings on power tools. Store the bit dry and clean to prevent corrosion and check tip condition before precision assemblies.
