ARP is one of the most renowned screw manufacturers for motorsport: well-known racing teams from Formula 1, Nascar and Indycar series trust the excellent quality.
The threads are rolled into high-strength steel. This non-cutting process does not interrupt the fibre flow, unlike thread cutting. On the contrary, the cold forming process hardens the structure of the surface.
The benefit lies in the high safety reserves of the most heavily loaded components in the engine.
