Product Description

HEX HEAD HEADER BOLTS
Designed for quick, easy installation of headers and heat-treated for extra strength. The special washer faced, smaller-than-standard hex head is ideal for tight spaces. These bolts are Grade 5 with a 7/16 hex head and a protective black finish, except where noted.

STAINLESS STEEL HEADER BOLTS

  • Bright ball burnish finish 304 stainless steel
  • Compact hex head and flange is ideal for use where space is minimal – typical on header flanges

SOCKET HEAD HEADER BOLTS

  • Black oxide coated
  • Compact socket head design is ideal for use where space is minimal – typical on header flanges

METRIC HEADER & EXHAUST MANIFOLD BOLTS

  • Black oxide coated
  • Compact socket head design is ideal for use where space is minimal – typical on header flanges

HEADER BOLT LOCK WASHERS

  • Black oxide coated
  • Designed for use with header bolts to prevent loosening caused by vibration
  • Helps maintain fastener clamp load for positive header flange seal

SOCKET HEAD HEADER STUDS

  • Black oxide coated studs
  • Cadmium plated hex nuts
  • Designed for small tube headers with adequate clearance around header flange bolt holes
  • Self-locking hex flange nuts are ideal for use where space is minimal and help maintain clamp-load for uniform flange seal

HEADER-TO-MUFFLER BOLTS

  • Cadmium plated Grade 5 steel
  • Stover lock nuts eliminate “old-style” split lock washers
