    Header Flange Bolts - Hex Head
    Mr. Gasket's grade-5 bolts with 7/16'' hex head are designed to handle the abuse of ultra-hot exhaust ports. Features a smaller than standard 7/16'' hex head which is perfect for tight-clearance headers. Part #720-3409 bolts feature a smaller, 3/8'' hex head and come with AN-style washers. In many cases you can even use a box end wrench to tighten your headers! Black oxide plated.

    Header Flange Bolts - Socket Head
    Save time work and solve the impossible tightening problems of some header installations with socket head bolts. Grade-8 and black oxide plated.
