- High-Strength Industrial Steel: Made from premium heat-treated materials with exceptional hardness. This tool is resistant to abrasion and won't easily deform or "round off" under heavy torque, ensuring years of reliable use.
- Precision Machined Finish: Every spanner undergoes surface treatment to ensure a smooth, burr-free finish. Its high corrosion resistance makes it a durable addition to any garage or professional workshop.
- Effort-Saving Operation: Designed for maximum grip on the castle-style nut. The precise fit reduces the risk of slipping, allowing you to apply force more effectively and complete your repairs with less effort.
- Compact & Portable: At only 60mm long, it easily fits into a tool roll or pocket, making it the perfect "trailside" tool for emergency clutch adjustments.
Mechanic's Maintenance Tip
The Right Way to Torque: Clutch nuts are often tightened to specific torque settings. When using this spanner, ensure it is fully seated over the "castles" of the nut before applying pressure. For best results, use a 1/2" drive extension or a dedicated T-handle to maintain even downward pressure while turning.

Worked great on Honda TRX90
I was working on a 72-Honda sl70 and needed this socket to tight the clutch shaft lock nut, worked perfectly. I tried several times (4 tear downs) to get the nut tight. I should've just bought this and been done. Oh well, job done and the socket ended up being and great value.Thanks,
Worked great for my Apollo 125. Spend a few bucks on this tool and save yourself a headache. You can put a torque wrench on this and make sure the nut is tightend down correctly. Don't be a hack and try to use a hammer and screwdriver or something on the clutch nut.....
Great tool
