Mr. Gasket Valve Cover Clamps are manufactured from high-quality steel and plated with chrome to give a fine finish. The valve cover clamps help to distribute bolt pressure more evenly for better sealing. These custom clamps are short in style and are meant to be used on covers with the help of more than 4 hold-down bolts. They facilitate the tightening of covers and minimize the bending of flange due to irregularities. The clamps can accomodate up to 5/16 diameter hold-down bolts.
