Fasteners are not just bolts. They are the clamp force holding your engine together under boost, RPM and cylinder pressure.
In our latest Prime Speedworks blog, we break down why selecting the right P1 Fastener material matters — from street builds through to high-boost drag, circuit and burnout applications.
Right material. Right application. Right result.
P1 Fasteners available through Prime Speedworks.
Prime Speedworks was built at the track, not in a boardroom.
With decades of real motorsport experience, we’ve gone fast across it all — V8 Supercars, Offshore Powerboats, Sprintcars, Midgets, and Drag Racing from Top Fuel to Super Sedan, including the brutal world of Drag-and-Drive.
We don’t chase hype — we back proven performance. Every product we support is chosen because it survives real racing, not because it looks good on a shelf.
If it doesn’t make you faster, stronger, or more reliable, it doesn’t belong at Prime Speedworks.
Prime Speedworks is proud to play a part in the Performance and Racing Industry in Australia and Worldwide, supporting industry bodies and initiatives.
