- Wedge-Locking Header Bolts
- Hex Head; 3/8-16 Thread X 3/4 in Black Oxide
- Engine Header Bolts; Wedge-Locking Technology; Hex Head Type; 3/8-16 Thread X 3/4 Inch Long; Black Oxide Finish; 16 Pcs in kit; Fits GM BB 396-502 exc 348 and 409, Ford 5.0L, SB 289-302-351W, Mopar 413
- Product Attributes:
- Diameter: 3/8-in.
- Category: Header Bolts
- Feature/Benefit: Wedge-locking Technology Eliminates Constantly Re-tightening Exhaust Collector Bolts; Blocks Bolt-loosening Rotation Caused By Vehicle Vibrations.
- Length: 3/4 Inch
- Applications: Fits Gm Bb 396-502 Exc 348 And 409, Ford 5.0l, Sb 289-302-351w, Mopar 413
- Part Type: Header 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 sixteen 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.
