Made in the USA, Stage 8's Grade 8 locking header bolts use a patented system that consists of a 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.

I know my header bolts will not come loose again. That alone is worth the cost. Top quality and excellent looks. Lots of trouble free miles ahead.

Stage Eight

Summit RacingSummit Racing Verified Purchase

Worked well. Used on a set of headers. Had to cut most of the locking tabs per instructions to install. One of the bolts was to big to install on close tube.
