Because of the additional sealing needed with vacuum systems, simply hand tightening the wing nuts may not be sufficient. These unique speed studs allow a quick, easy removal with a 1/2 inch socket. The lightweight, aluminum body is clear anodized for a long lasting finish. Set screws may be secured to the head or to the aluminum body. Recommended only for cast aluminum valve covers, tightening stamped steel covers will cause them to warp at the rail resulting in worse sealing. Includes (2) 1/4 inch-20 x 1-1/2 inch set screws and (2) 4-3/8 inch tall aluminum body with 1/2 inch hex head


  • Allows tightening of valve covers with 1/2" socket
  • Clear anodized aluminum body
  • Set screws can be installed in heads or in aluminum body
  • Sold as a pair
