When installing headers you will need header bolts, factory exhaust manifold bolts won't work. These Mr. Gasket Header Bolts are grade 8 for strength, black oxide coated, and have a compact 3/8 inch hex head that is ideal for use where space is minimal - your typical header flanges. Includes (12) 3/8 inch-16 x 3/4" bolts.


  • Mini 3/8 inch hex head for better socket clearance
  • Grade 8
  • Black oxide coated
