Wedge-Locking Header Bolts; Hex Head; 3/8 dia. X 3/4in Black Oxide; 12 Pcs
Engine Header Bolts; Wedge-Locking Technology; Hex Head Type; 3/8-16 Thread X 3/4 Inch Long; Black Oxide Finish; 12 Pcs in kit; Fits GM V6, SB 265-400, Buick, Olds, Pontiac '79 and earlier, Mopar BB 383-440 exc 413, AMC V8's w 3/8" bolts
PROFORM Wedge-Locking Header 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 twelve Hex Head, Grade 8 (12.9) steel bolts (3/8"-16 thread, 3/4" long) with a black oxide finish, and pre-assembled Wedge-Locking Washers.
This is a Universal/Non Application Specific Product. To install this part, you made need to cut, weld, or make other modifications to your vehicle.
