Rated 2 out of 5 by from Locking Header Bolts Too Short I purchased the "Mr Gasket Locking Header Bolts" about a month ago. The quality of the bolt looks great but, they are too short in length to use for mounting header's. The bolts are 3/8"-16 NC x3/4". If you take into account the 3/8" header mounting flange, plus the 1/16" gasket, that leaves you with a grip length of one 5/16". What is required is a 1.0" bolt which, will give a grip length of 9/16" thus preventing the possibility of the threads pulling out.
