Description

The ARP 100-1208 is a set of 16 header bolts designed for engine applications. These bolts feature a 3/8-16 thread size and a 0.75-inch underhead length. Constructed from 8740 chromoly material with a black oxide finish, they offer a tensile strength of 170,000 psi.

The kit includes 12-point fasteners for easier access with a socket, and the material is substantially stronger than Grade 8 hardware. ARP has been a leader in fastener technology since 1968, producing a wide range of engine and driveline hardware.
