These header & collector bolts are the same bolts used in every set of Hedman "Hedders." Even the best headers may provide practically zero bolt clearance. But, with Hedman's smaller 3/8" wrench size, these bolts have a smaller head than standard for more clearance to install, tighten, or remove. Kits include sixteen bolts and are available with either a black oxide or zinc coating.
Collector Bolt Kits come complete with all the zinc-coated fasteners required to bolt up one pair of collectors. "Flat Gasket" or "Ball & Socket" style collector bolts available.
