OTK Chain Stretcher Jam Bolt M10 Long

The OTK Chain Stretcher Jam Bolt M10 Long (part number 0110.B0A) is a genuine OTK plastic jam bolt used in conjunction with the OTK M10 chain stretcher system. Once chain tension has been set using the main stretcher bolt (0110.B0), this jam bolt is threaded against it to lock the adjustment in place and prevent it from backing off during a session. This is the long version, finished in red plastic, designed for use in 100cc OK and KF class applications.

Chain tension management is a fundamental part of kart setup. On OTK chassis, the M10 stretcher and jam bolt work as a pair: the stretcher bolt applies the tension, and the jam bolt locks it. Running without a correctly fitted jam bolt risks the tension setting shifting under vibration, which can lead to chain slap, increased wear or chain derailment. Replacing a worn or damaged jam bolt is a straightforward task that should be part of any chain system service.

Buying Advice

This is the jam bolt only — it does not include the main stretcher bolt. The complete chain tensioning system on OTK chassis uses two parts: the stretcher bolt (0110.B0) and this jam bolt (0110.B0A). If you are replacing both, order each part separately. If you are unsure which chain stretcher length is correct for your engine class, refer to your engine mount setup documentation or check with your mechanic before ordering.
