Mr. Gasket HEADLOCK Locking Header Bolts

Burning your hands on headers or the exhaust manifold when bolting them on just became a thing of the past. Mr. Gasket HEADLOCK locking header bolts simplify header installation with high-strength, 2-in-1 self-locking bolts that eliminate the need for lock washers. Designed for the performance engine builder, these innovative, patent-pending fasteners have 24 equally spaced serrations in the face of the hex head. The bolts grab and lock on to your manifold surface, virtually eliminating the chance that one might back out from vibration or because of the varying expansion rates of different metals. Mr. Gasket HEADLOCK locking header bolts are available for numerous domestic applications, including Chevrolet, Chrysler, Ford, AMC, Oldsmobile, and Pontiac. They're manufactured from stainless steel, designed to withstand tensile strengths of 150,000 pounds per square inch, and come with a bright polished finish.

Mr. Gasket Header Installation Kits

These kits from Mr. Gasket are complete header gasket and fastener installation kits. Mr. Gasket was the first to incorporate slotted mounting bolt holes at the ends of each exhaust gasket. This allows the gasket to be installed without removing the header flange entirely from the cylinder head, making installation faster and easier. Premium Ultra-Seal exhaust and collector gaskets provide excellent heat resistance, and conform to and seal minor surface irregularities. Mr. Gasket header and collector bolts provide the proper clamp-load to seal flange mating surfaces. All gaskets and fasteners necessary for header installation are included.

Stage 8 Locking Header Fastener Kits

Stage 8's Grade 8 locking header fasteners use a patented system that consists of a grooved hex-head bolt or nut, 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 fasteners are tightened down, they won't back out, eliminating leakage and blown header gaskets from loose bolts.
