Socket bit 1/4" 6-point 5.5 mm long Proxxon PR23769

Proxxon PR23769 is a long 6-point socket bit with a 1/4" drive and a 5.5 mm head, designed to reach recessed fasteners and work in confined spaces. Made for use with compatible screwdriver handles, ratchet drivers or adapter sets, this socket bit combines extended reach with a 6-point profile for secure engagement on hexagonal heads. It is intended for precision mechanical, electronic and light automotive work where access and accurate torque transfer matter.

Advantages

The long 5.5 mm 6-point head reduces rounding of screw and bolt corners and ensures a tighter fit compared with 12-point designs. Its 1/4" drive end fits common handles and ratchets, offering versatility across a range of driver systems. The extended length improves access to recessed or hard-to-reach fasteners without requiring additional extensions, supporting precise, stable operation in small assemblies and narrow cavities.

Suitable for

• Precision mechanical assembly and maintenance
• Electronic device repair and component fastening
• Light automotive and motorcycle tasks with confined fasteners
• Workshop use where a longer reach and 6-point engagement are required

Key specifications

• Drive size: 1/4" (6.35 mm)
• Head profile: 6-point (hexagon)
• Head size: 5.5 mm
• Overall length: long type for extended reach
• Compatibility: for use with 1/4" screwdriver handles, ratchets and adapters

How to use

Insert the 1/4" drive end into a compatible handle, ratchet or adapter and select the appropriate direction on the tool. Position the 6-point head squarely onto the fastener and apply steady torque to avoid slipping. Use controlled force when working on electronic or delicate mechanical assemblies to prevent damage. After use, store the socket bit in a protective case or organizer to maintain its geometry and prevent corrosion.

Usage recommendations

For best results, match the 5.5 mm 6-point socket bit to fasteners of the same size and avoid using excessive impact tools unless the bit is specified as impact-rated. Regularly inspect the bit for wear before precision tasks and combine with appropriately sized handles and torque-limited drivers when working on sensitive components.
