Suitable for panels as thin as 0.64 mm, the 56 Spring-Loaded Plunger features a thread-in design that helps to prevent lost hardware. Stay-open/nonstay-open options provide versatility for fastening and unfastening by hand when mounting doors, panels and other hardware components in applications with limited space. Its accentuated head styles provide ample grip, while an optional over-molded head allows engineers to designate access points or color code access to application requirements. A retractable-pin design simplifies the positioning of sliding components.
