When installing headers you will need header bolts, factory exhaust manifold bolts won't work. These Mr. Gasket Header Bolts are grade 5 for strength and black oxide coated. If you've ever had a set of headers where a socket just seemed it wouldn't fit these might be your answer. These bolts have a socket head or Allen key drive in the center and that compact socket design is ideal for just that problem. Sold as a set of 12.

Features:

  • Compact socket head - ideal for tight spaces
  • Black oxide coated
  • Grade 8
  • 5/16"-18 x 3/4" Long
  • Set of 12 pieces
