## Long description

Proxxon PR23374 1/2" Spline M14 x 100 mm long is a long spline socket bit designed for engaging M14 spline-headed fasteners. With a 1/2" drive interface and 100 mm overall length, this tool provides extended reach for working in recessed, narrow, or hard-to-access locations. It is made for mechanical and automotive applications where precise engagement with spline bolts and studs is required, and it is compatible with standard 1/2" ratchets, torque wrenches and impact adapters when used with appropriate adapters or holders.
Advantages
The long 100 mm shaft gives improved access to fasteners located deep inside assemblies without compromising control. The spline profile ensures precise contact with fastener faces to reduce rounding and slippage. The 1/2" drive interface provides a robust connection to common hand and power tools, allowing use with torque tools for controlled tightening. The bit is engineered for durability under workshop conditions and repeated use.

 Automotive repairs involving spline-headed bolts and studs
 Mechanical assembly and disassembly in engines and gearboxes

How to use
Select a compatible 1/2" drive ratchet, breaker bar or torque wrench and secure the spline bit into the drive. Position the spline profile squarely onto the matching M14 fastener to ensure full engagement. Apply controlled torque while maintaining axial alignment to avoid slippage or damage to the fastener head. For impact use, fit a suitable impact-rated 1/2" adapter and follow the power tool manufacturer's safety guidelines.
Usage recommendations
Inspect the spline profile and fastener for wear before use. Use correct torque settings where specified and avoid applying excessive force that could deform the spline or the fastener. Store the bit in a dry toolbox to prevent corrosion and extend service life.
