Hex Socket Bit 9 mm 3/8" Drive 50 mm Proxxon PR23577

Proxxon Hex Socket Bit 9 mm 3/8" Drive 50 mm is a precision tool insert designed to work with standard 3/8" drive ratchets and extensions. It is intended for tightening and loosening hex (Allen) socket-head fasteners where a 9 mm size is required. The 50 mm overall length provides reach into recessed or partially obstructed fasteners while maintaining compatibility with common mechanical and automotive tool sets.

Advantages

The bit is manufactured to Proxxon quality standards for consistent fit and reliable engagement with hex fasteners, reducing wear on screw heads. Its 3/8" drive interface ensures compatibility with a wide range of ratchets and torque tools, enabling controlled torque application. The 50 mm length offers a balance between access and control, allowing work in confined spaces without sacrificing stability during use.

Suitable for

• Automotive repair and maintenance tasks involving hex socket screws
• Mechanical assembly and disassembly where a 9 mm hex insert is required
• Industrial and workshop use with 3/8" drive ratchets and extensions
• Maintenance tasks requiring access into recessed or partially obstructed fasteners

Key specifications

• Socket size: 9 mm hex (Allen)
• Drive type: 3/8" drive
• Overall length: 50 mm
• Compatibility: designed for use with 3/8" ratchets, torque wrenches and extensions
• Application: manual and torque-controlled tightening/loosening of hex socket-head fasteners

How to use

Select a compatible 3/8" drive ratchet, extension or torque wrench and attach the Proxxon 9 mm hex socket bit by pressing or snapping it into the tool's drive. Position the bit squarely into the fastener head to ensure full engagement, then apply controlled torque to tighten or loosen the fastener. For recessed fasteners, use an extension on the drive to reach the workpiece while maintaining straight alignment for best engagement.

Usage recommendations

Inspect the fastener and bit for damage before use, and avoid using worn or rounded bits to prevent stripping. When applying high torque, use a torque wrench or a properly rated ratchet and follow the fastener manufacturer's torque specifications. Store the socket bit in a dry tool organizer to prevent corrosion and preserve precise fit.
