The PF11PM series consists of large knob, spring-loaded captive panel screws with a plastic PEM® C.A.P.S.® housing for tool-free access. Flare-mounted with metric threading, it installs into sheet materials up to HRB 80 or HB 150 hardness. The knob is PC/ABS (UL 94V-0, halogen-free), colored black by default; the screw and retainer are hardened carbon steel; the spring and clip are 300 series stainless steel. It provides a minimum 0.25 mm float in all directions and uses a #2 Phillips driver. The dot pattern on the head identifies metric threads. All variants in the series share these construction materials, float capability, and installation requirements.
