Stage 8 Locking Header Collector Bolt Kit - 3/8"-16 Thread, Hex Head - Locking - Stainless Steel - Natural - Set of 6

Stage 8 locking header collector bolts use a patented system that consists of a Grade 8 grooved hex-head bolt, a retainer, and a snap clip. The retainer fits over the bolt head and locks the bolt against the header tube, and the snap clip holds the retainer in place. Once Stage 8 header bolts are tightened down, they won't back out, eliminating leakage and blown header gaskets from loose bolts. Made in the U. S. A.
