Impulse Exhaust Header Bolt Set

Small 5/16" hex head allows header bolts to be used in areas with limited space

Impulse header bolts are hi-tensile bolts with a small 5/16" hex head to allow the header bolts to be used in areas with limited space. The bolts can also be tightened much harder than cap screws which prevents leaking or blown exhaust gaskets. The header bolt set includes 12 x 5/16" UNC grade 8 bolts 1" long with a small 5/16" hex head.
