Mr. Gasket 6080 Super Intake Manifold Bolt
Mr. Gasket Super Intake Manifold Bolts feature a generous underhead radius for added strength and a wide washer faced head to spread the clamping force evenly on the manifold for a positive gasket seal. Extra thick heat treated flat washers are included to assure accurate torque application and to prevent galling aluminum intake manifolds. These Grade 5 bolts feature a smaller-than-standard hex head which facilitates installation and are black oxide coated to provide a protective finish.
