## Long description

Proxxon spline socket 1/2" M12 x 100 mm long PR23373 is a long spline socket designed for use with compatible 1/2" drives and ratchets. The socket features an M12 spline profile and a 100 mm overall length, allowing it to reach recessed or otherwise hard-to-access spline bolts and nuts. It is intended for professional and hobby use in automotive, mechanical repair and general maintenance tasks where deep-set fasteners are encountered.
Advantages
The long 100 mm length provides extended reach while maintaining a compact outside diameter suitable for tight spaces. The M12 spline profile ensures positive engagement with spline fasteners, reducing slippage and rounding. Manufactured by an established tool maker, the socket is made from a hardened chrome-vanadium style alloy with a polished finish to resist corrosion and allow easy cleaning after use.
Suitable for
 Removing and installing deep-set M12 spline bolts and nuts
 Automotive drivetrain and transmission work where access is restricted
 Mechanical assembly and maintenance in workshops and garages
 Use with 1/2" drive ratchets, breakers and extensions for increased leverage
Key specifications
 Drive size: 1/2"
 Spline profile size: M12
 Overall length: 100 mm
 Socket type: long spline socket
 Material: hardened alloy steel with polished finish
How to use
Select a compatible 1/2" drive tool such as a ratchet, breaker bar or extension. Fit the socket onto the drive square, align the M12 spline profile with the fastener, and apply steady torque while maintaining axial alignment to avoid cam-out or thread damage. For stuck fasteners, use controlled incremental force and consider penetrating lubricant and heat only if appropriate for the assembly. Inspect the socket and fastener after use for wear or damage.
Usage recommendations
Use the socket with the correct 1/2" drive tools and avoid excessive impact on thin-walled or damaged fasteners. Store the socket in a dry toolbox and keep the mating faces clean to preserve fit accuracy. Replace the socket if deformation or cracking is observed.
