How it’s made: ARP bolts


Automotive Racing Products (ARP) started making bolts, nuts, and other fasteners in Southern California 50 years ago. Its start-to-finish handling of every step of manufacturing, from material selection to packaging, has given the company a reputation for quality fasteners that hold up to serious abuse. ARP’s products can be found in everything from Top Fuel dragsters to F1 race cars, 400-mph land speed streamliners, and show-winning hot rods. It is even contracted for specialized fasteners used in aerospace applications.
