Exhaust Collector Bolts and Nuts; Wedge-Locking Washer Technology; Hex Head Type; 3/8-16 Thread X 1.25 Inch Long; Black Oxide Finish; 6 Pcs in kit
PROFORM Wedge-Locking Exhaust Collector Bolts ELIMINATE the need to constantly re-tighten collector bolts, and without the need for clips, pins, racing-wire, chemicals or gunk. The secret is in the Wedge-Locking Washer's super-hardened external teeth that bite into the bottom of the bolt head and the top flange surface. Vibrations that normally cause other bolts to loosen, are blocked by the wedge-locking action that uses tension, instead of friction to stay snug. In fact, contact with oil actually facilitates the effect. Installs/uninstalls with a normal wrench, lubricate, and then reuse. Each set comes with six Grade 8 bolts (3/8-16 thread, 1 long) with a black oxide finish, six nuts and six pairs of Wedge-Locking Washers.
