Mr. Gasket 6081MRG Super Intake Manifold Bolt

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 big-block Chevys, these durable 1.25-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 16.
