These specialty fasteners are widely used for securing panels, hoods and scoops; providing an easily operated, positive acting, and shake proof mounting solution. Pro-werks self-eject quarter turn fasteners are ideal for applications where it is beneficial to retain the fastener on the panel after the buttons are released. The integral spring assists in lifting the fastener, keeping it elevated for quick re-assembly, and the special two hole mounting plate retains the button to the panel. Self-ejecting buttons are not for every installation, but where they are needed it’s a pretty slick system. Available in a broad selection of sizes, types and grip lengths; all are suitable for steel, aluminum, fiberglass and composite panel installations. Steel construction and silver zinc plated for lasting corrosion resistance. Conveniently packaged in quantities of 10, and it never hurts to have a spare button or two in the tool box either!
