These OMP seat mounting bolts are designed for racers and enthusiasts seeking a secure and compliant method to attach their seats to side or base mount frames. The key benefit is ensuring FIA regulation compliance for safety-critical mounting points. A potential caveat is that these are specifically for M8x1.25 threads and compatible frames, requiring precise fitment. This set includes 4 self-locking bolts with integrated load-spreading safety washers and hex heads, specifically engineered for racing seat installations.

Each set includes 4 bolts, which is the standard quantity required for mounting one seat.
The thread size is M8 x 1.25.
These bolts are specifically designed for racing seats and compatible mounting frames. They are not intended for standard road car seats unless they use a similar FIA-compliant mounting system.
Self-locking means the bolt has a feature (often a nylon insert or deformed threads) that creates friction to prevent it from loosening due to vibrations, a common issue in performance driving.
The integrated washer helps to spread the clamping load over a larger area of the seat bracket and the mounting surface, reducing the risk of material fatigue or damage.
You will need an appropriate size hex wrench (Allen key) to tighten the bolts. A torque wrench is recommended for precise tightening to manufacturer specifications, if available.
While steel bolts can be reused, the self-locking feature may be compromised after multiple installations. For critical safety applications, it is recommended to replace self-locking fasteners if they show signs of wear or if torque values cannot be consistently achieved.
Verify that the subframe or mount bracket has M8 x 1.25 threads. This bolt set is not compatible with other thread sizes.
Ensure the integrated self-locking mechanism is functioning correctly. Check that the seat bracket and subframe are properly aligned and that the bolt is seated flush before tightening. If the issue persists, the bolt may be damaged and require replacement.
Ensure you are using the correct size hex wrench and that the bolt is threading in straight. Check for any debris in the threaded hole or on the bolt.
