## Summary description

Proxxon spline socket 1/2" M10 x 100 mm (PR23372) is a long 1/2-inch drive socket designed for spline-head fasteners with an M10 size and 100 mm length. It provides extended reach for working in recessed or hard-to-access areas, suitable for hand ratchets or torque tools with a 1/2" drive. Ideal for automotive, mechanical maintenance and assembly tasks.

## Long description

Proxxon spline socket 1/2" M10 x 100 mm PR23372 is a long, precision-machined socket for spline-head fasteners with an M10 profile. Designed for a 1/2" drive, this 100 mm long socket gives extended reach for working in recessed, narrow or hard-to-access locations. Its spline profile allows engagement with spline-head bolts and offers multiple contact points to reduce rounding of fasteners during removal or installation. The tool is intended for use in automotive, mechanical maintenance and general assembly tasks where controlled torque and access are required.
Advantages
The long 100 mm length increases accessibility in deep or obstructed mounting situations while maintaining torque transfer from a 1/2" drive. The spline geometry distributes load across several flanks of the fastener, reducing the risk of damage compared with single-point drives. Machined to precise tolerances, the socket ensures secure fit and consistent performance with hand ratchets and compatible torque tools. Its hardened construction is suitable for repeated workshop use and provides reliable engagement with spline-head fasteners.
Suitable for
Accessing spline-head bolts in recessed engine bays and transmission housings
Mechanical maintenance and repair where extended reach is needed
Assembly and disassembly tasks on vehicles, machinery and equipment
Use with 1/2" drive hand ratchets, breaker bars and torque wrenches
Key specifications
Drive size: 1/2"
Fastener profile: spline, M10 nominal fit
Overall length: 100 mm
Material: hardened tool steel (factory heat-treated)
Finish: corrosion-resistant surface treatment
How to use
Select the socket that matches the spline fastener size and attach it securely to a compatible 1/2" drive hand ratchet, breaker bar or torque wrench. Position the socket squarely on the fastener to ensure full engagement of the spline profile, then apply steady torque in the required direction. For removal, apply controlled force to avoid slippage; for tightening, use a calibrated torque tool when precise torque values are required. After use, wipe the socket clean and store in a dry location to maintain the finish and fit.
Usage recommendations
Use this long spline socket with appropriate hand or torque tools rated for the required torque. Avoid impact tools unless the socket and fastener specifications permit impact use. When working in confined spaces, ensure stable support and clear access to avoid sudden tool slips that may damage the fastener or surrounding components.
