Can you make a custom or one-off fastener for my build?Updated 2 hours ago
Yes. Custom specialty fasteners for high-performance, rare and unique engine builds are something we specialise in. You work directly with our team to spec a fastener for strength, reliability and performance in your application.
When custom is the right call
- Your engine or platform is not in our catalogue
- A swapped engine, aftermarket head, or deck plate has changed the required stud length or grip
- Your power or boost target exceeds the 7200 Series rating — 800 hp / 30 psi on gas, 1,000 hp / 60 psi on diesel
- You are building a race-only or one-off engine with non-standard geometry
- You need a batch produced for a shop programme or a limited production run
What to send us
The more of this you can provide, the faster we can quote:
- Engine make, model, displacement and year
- What the fastener does — head studs, main studs, rod bolts, something else
- Thread size and pitch, and required overall length and grip length
- Quantity needed
- Power target, boost level and intended use — street, drag, pulling, endurance
- Drawings, photos, or a sample of the original fastener if you have one

A note on warranty
Custom and made-to-order fasteners are quoted individually and their warranty terms are confirmed as part of the quote, since coverage depends on the application they are specified for.
