Description

Mr. Gasket Super Intake Manifold Bolts have a smaller-than-standard hex head with a special under-head radius for added strength and a wide washer-faced head that spreads the clamping force evenly. Designed specifically for small-block Chevys, Chryslers, and AMCs, these durable 1.062-inch-long 3/8-16 bolts come with extra-thick heat-treated flat washers that deliver a more uniform torque and prevent galling on aluminum intake manifolds. They're heat-treated to Grade 5 specs, a perfect fit for tight spaces, have a protective black-oxide finish, and come in a set of 12.
