Mr. Gasket Header Collector Bolt Kt

This Mr. Gasket Header Collector Bolt Kit has self-locking nuts to hold your collector(s) securely to your header(s). Stover lock nuts eliminate loss of the old-style lock washers because they’re not needed. Includes three 3/8-16 x 1 inch cadmium plated grade 5 bolts and three matching Stover lock nuts. Enough hardware to do one 3-bolt collector.
