Bit for Hexagon Screws Wera 05056685001 5 mm tip, 25 mm length

Replacement bit designed for hexagon (internal hex/Allen) screws from Wera, featuring a 5 mm tip diameter and a 25 mm overall length. The bit is intended for use with compatible bit holders, screwdrivers and impact or hand tools to provide a precise fit in hex socket heads. It offers repeatable engagement for assembly, maintenance and repair tasks where correct torque transfer and reduced cam-out are required.

Advantages

The Wera 5 mm hexagon bit is manufactured to provide a consistent geometry that ensures stable contact with internal hex screws. Its 25 mm length balances reach and control, allowing use in confined spaces while maintaining comfortable handling. The bit is compatible with common 1/4" hexagonal bit holders and quick-change systems, delivering reliable torque transfer and reduced rounding of screw heads under normal working loads.

Suitable for

• Assembly of furniture and fixtures with hex socket fasteners
• Maintenance and repair of machinery and equipment using internal hex bolts
• Electronics and appliance servicing where a precise 5 mm hex tip is required
• Work with portable drivers, bit holders and ratchet handles

Key specifications

• Tip shape: Hexagon (internal hex / Allen)
• Tip size: 5 mm
• Total length: 25 mm
• Drive compatibility: 1/4" hexagonal bit holders and compatible quick-change systems
• Material and finish: hardened tool steel with corrosion-resistant coating (manufacturer standard)

How to use

Insert the 5 mm hex bit into a compatible 1/4" bit holder, quick-change chuck or screwdriver handle. Align the bit tip with the internal hex recess of the screw and apply steady axial pressure while turning the driver to engage the fastener. For tight or high-torque applications, ensure the bit is fully seated in the socket to minimize slippage and wear. Use appropriate torque settings on powered drivers and consider a hand tool for final tightening to avoid over-torquing sensitive fasteners.

Usage recommendations

Inspect the bit tip before use for deformation or rounding; replace if damage is evident. Match the 5 mm tip to the corresponding screw size for best fit. Store bits in a protective case to prevent corrosion and mechanical damage. When using impact drivers, confirm the bit and holder are rated for impact use.
