P1 Fasteners
The P1 Fasteners collection at Prime Speedworks is focused on critical engine hardware for performance and motorsport engine builds. P1 manufactures high-strength head stud kits, main stud kits, rod bolts and custom fasteners for aftermarket, racing and demanding performance applications, with production based in Rogersville, Missouri in the United States.
P1’s own manufacturing information highlights a detailed fastener production process including individual racking, vacuum furnace heat treatment and metallurgical control. The brand’s range covers head studs, main studs and rod bolts, with attention placed on consistency, strength and precision throughout the manufacturing process.
Prime Speedworks stocks the P1 Fasteners range in Australia, including head studs, main studs and rod bolts for popular performance platforms such as LS, LSX, Honda B-Series, Honda K-Series, Toyota 2JZ and other serious engine combinations. The Prime Speedworks P1 range includes options such as Toyota 2JZ head stud kits for OEM blocks and Dart blocks with 11mm threads, 12-point nuts, E190 series material and black oxide finish.
In a serious engine build, fasteners are not a place to gamble. Cylinder pressure, boost, RPM, combustion load and crankcase movement all place huge demand on the hardware holding the engine together. The right head stud, main stud or rod bolt package helps maintain clamping force, supports gasket sealing, improves bottom-end security and gives the engine builder more confidence when the combination is pushed hard.
Whether the build is a boosted 2JZ, high-RPM Honda, LS street/strip engine, RB race package or a dedicated drag car, P1 Fasteners suit applications where reliability and repeatability matter. Prime Speedworks supports the P1 range with a technical, build-focused approach to help customers select the correct fastener package for the engine platform and intended use.

Why buy this collection from Prime Speedworks
Fasteners are one of the most critical parts of any serious engine build. They may not be the flashiest component in the engine bay, but they are responsible for keeping the cylinder head clamped, the mains stable and the rotating assembly under control when cylinder pressure and RPM increase.
Prime Speedworks supplies P1 Fasteners with a real-world understanding of how these parts are used in Australian performance builds. We work with workshops, engine builders, racers and serious enthusiasts who need parts selected for the application — not just ordered because they fit the thread.
Our approach is based on engine combination, boost level, block type, cylinder head, gasket package, intended power level and racing use. Whether you are building a street-driven turbo engine or a dedicated race motor, Prime Speedworks can help supply the correct P1 head studs, main studs or rod bolts to suit the job.
P1 is a strong fit for builders who care about clamp load, repeatability, material quality and confidence under load. This is hardware for engines that are expected to work.
