The PF51 is a low-profile, spring-loaded captive panel screw designed for easy tool or finger operation with a Phillips recess, suitable for attaching thin metal panels where repeated access is required. It installs into sheets as thin as 0.5 mm and is compatible with M4 threading. The screw includes a spring mechanism to maintain tension and prevent loss of hardware during disassembly. Available in standard black coloring and designed for use in applications requiring compliance with UL standards and corrosion resistance. The exact dimensions and specific performance ratings are consistent across the PF50/PF51/PF52 series.
