Socket bit Wera 8740 a 2 mm 1/4" for screwdriving – steel, precision fit

Wera Socket bit 8740 a 2 mm 1/4" for screwdriving – steel, precision fit is a compact 1/4" drive bit engineered for accurate engagement with small cross and slotted screw heads. Manufactured from hardened steel, this bit is intended for repeated use in delicate fastening tasks where precise tip geometry and consistent torque transfer are required. It is compatible with standard 1/4" bit holders, manual drivers and compact power drivers used in electronics, light assembly and general maintenance.

Advantages

The hardened steel construction ensures wear resistance and a long service life under frequent use. Precision machining of the tip provides a secure fit in screw heads to reduce slippage and stripping. The 1/4" drive interface allows straightforward mounting in common bit holders and drivers, enabling quick tool changes and stable torque transmission. Its compact length and accurate profile make it suitable for working in confined areas and on small fasteners.

Suitable for

• Electronics assembly and repair
• Precision mechanical maintenance
• Small appliance servicing
• Model building and hobby work
• Controlled fastening tasks in production lines

Key specifications

• Bit type: socket bit with 1/4" drive
• Tip size: 2 mm
• Material: hardened steel
• Fit: precision-machined tip for accurate engagement
• Compatibility: designed for use with 1/4" bit holders, manual drivers and compact power drivers
• Typical applications: small screws and confined working spaces

How to use

Select the 1/4" bit holder or driver compatible with your tool and insert the Wera 8740 a 2 mm bit until it seats securely. Align the bit with the screw head to ensure full engagement of the tip before applying torque. For manual tightening, apply steady pressure and controlled rotation; for power drivers, use low to medium speed and appropriate torque settings to avoid overdriving or damaging small screw heads. Remove the bit by withdrawing it from the holder when the task is complete and store it in a dry place to minimize corrosion.

Usage recommendations

Use the bit with correct torque settings and appropriate driver speed to preserve tip geometry. Inspect the tip regularly for wear and replace if rounding or chipping is observed. When working on sensitive electronic components, combine the bit with an ESD-safe driver or take other electrostatic discharge precautions.
