Socket bit 1/4" 6‑point 5 mm Hartsson 17A105Z

Hartsson 1/4" 6-point 5 mm socket bit is a compact attachment for 1/4" drive ratchets and bit holders, designed for secure engagement with hex fasteners. The six-point profile fits firmly around bolt and screw heads to minimise cam‑out and rounding, making it suitable for precision assembly, maintenance and repair tasks in automotive, electronics and household environments. The small 5 mm size is intended for use on small to medium hex fasteners where control and access are important.

Advantages

The six-point geometry ensures an even distribution of torque across the fastener faces, reducing the risk of damage to hex heads. Its 1/4" drive interface provides broad compatibility with common ratchets, quick-change bit holders and compact hand drivers. The compact length and solid construction allow access to confined spaces while maintaining sufficient torsional strength for routine fastening and loosening tasks.

Suitable for

• Assembly and disassembly of small hex bolts in electronics and appliances
• Automotive trim and interior fastening tasks
• General household repairs and furniture assembly
• Maintenance work where a compact 1/4" drive bit is required

Key specifications

• Drive size: 1/4" (6.35 mm) compatible
• Socket profile: 6-point (hex) design
• Bit size: 5 mm hex
• Intended use: manual ratchet and bit holder applications
• Suitable environments: automotive, electronics, household maintenance

How to use

Insert the socket bit into a compatible 1/4" drive ratchet or quick-change bit holder until it locks in place. Position the 5 mm hex socket onto the fastener, ensuring full engagement of the six-point profile before applying torque. Turn the ratchet or driver in the required direction to tighten or loosen the fastener, applying steady, controlled force to avoid slippage. After use, withdraw the bit and store it in a bit holder or toolbox to prevent corrosion or damage.

Usage recommendations

Use the bit with tools rated for 1/4" drive and avoid excessive impact or torque beyond hand-tool limits. Inspect fastener heads and the bit tip for wear before use; replace the bit if rounding or deformation is visible to maintain secure engagement and prevent damage to fasteners.
