Stage 8 Grade 8 locking header collector 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.

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.

Installing headers can sometimes be a real pain, due to the tight spaces and the location and shape of the tubes. Mr. Gasket can help make installation a little easier and also help prevent annoying exhaust leaks from under-tightened header bolts. They have both the socket-head and hex-head styles of header bolts available. Hex types are heat-treated Grade 5 steel and have smaller-than-standard heads to ease access in tight spaces. Socket-head bolts are made from stronger Grade 8 steel for added ruggedness and they're great for those really difficult-to-reach spots. Both styles have a protective black oxide finish.

Typical aftermarket exhaust manifold bolts are much shorter than stock which after numerous heat cycles can cause them to fatigue and start to stretch, leading to exhaust leaks and possible breakage after repeated re-torques. The finish and coating on most of these bolts can also lead to premature corrosion and zinc embrittlement. Replace damaged or corroded exhaust manifold bolts with BD Diesel class 10.9 bolts and spacers which improve thermal durability to stand up to the heat and non-Zinc plated fasteners prevent zinc embrittlement. Order the kit recommended for your vehicle and engine application. BD Diesel exhaust manifold bolt and spacer kit #1041483 details: * Exhaust spacers ensure fastener operates in elastic stretch without fracture or permanent yield * Class 10.9 hardware * Non-zinc plated fasteners prevent zinc embrittlement * Includes 16 exhaust spacers (18mm) * Includes 16 flange head exhaust bolts (M8x1.25 – 40mm 10.9)
