Mr. Gasket HEADLOCK Locking Header Bolts make installing headers easy thanks to their high-strength 2-in-1 self-locking design that eliminates the use of lock washers. These innovative fasteners feature 24 equally spaced serrations in the face of the hex head that grab and lock on to the manifold surface. This eliminates the chance of them backing out from vibration or because of metal expansion. Manufactured from stainless steel, these bolts are designed to withstand tensile strengths of 150,000 pounds per square inch. They also have a high quality bright polished finish.
