## Summary description

Proxxon PR23371 is a long spline socket bit with 1/2" drive, sized M8 and 100 mm length. Designed for use with 1/2" drive ratchets and torque tools, it provides engagement for spline fasteners in mechanical and automotive applications. The extended length helps reach recessed or hard-to-access spline bolts and studs.

## Long description

Proxxon PR23371 is a long spline socket bit with a 1/2" drive, sized M8 and 100 mm overall length. It is engineered to engage spline fasteners reliably when used with 1/2" drive ratchets, extension bars and torque tools. The extended 100 mm length provides additional reach to access recessed or otherwise hard-to-reach spline bolts and studs in mechanical and automotive applications while maintaining a compact cross-section suitable for confined spaces.
Advantages
The spline socket bit offers precise engagement with spline heads to reduce rounding and slipping under load. Its 1/2" drive interface ensures compatibility with common hand and power torque tools. The 100 mm long shaft improves accessibility to deep-set fasteners, and the M8 profile matches standard spline fastener sizes used in many vehicle and machinery assemblies. The tool is designed for repeatable fit and safe torque transfer when used with appropriate torque-limiting devices.
Suitable for
Removing and installing M8 spline bolts and studs in engines and gearboxes
Working in narrow or recessed compartments where extra reach is required
Use with 1/2" drive ratchets, torque wrenches and extensions in maintenance and repair
Mechanical and automotive assembly or disassembly tasks requiring precise spline engagement
Key specifications
Drive size: 1/2"
Bit profile: spline (M8)
Overall length: 100 mm
Suitable for use with ratchets, torque wrenches and extensions
Intended for mechanical and automotive spline fasteners
How to use
Select the Proxxon PR23371 spline socket bit when the fastener head matches an M8 spline profile and extra reach is required. Fit the bit to a compatible 1/2" drive tool or extension, ensure the tool and fastener are aligned, and apply torque gradually. When torque accuracy is required, use a calibrated torque wrench and avoid exceeding the tool or fastener rated torque. Inspect the bit and fastener for damage before use and replace the bit if wear or deformation is present.
Usage recommendations
Use with a socket extension or universal joint where needed to access angled or recessed fasteners. Keep contact surfaces clean and avoid applying impact forces with hand spline bits unless they are specified for impact use. Store the bit in a dry place to prevent corrosion and check compatibility with the fastener profile before applying high torque.
