Description

The ARP 400-1207 is a set of 12 stainless steel header bolts. These bolts are designed with a compact 12-point head, allowing for easier access in tight spaces near headers. They offer 15 percent greater strength than Grade 8 steel and are both heat and corrosion resistant.

The bolts feature a polished finish, a 3/8 in.-16 thread size, and a 0.750 inch underhead length. The required wrench head size is 5/16 inch. This kit is considered universal for header applications.
