PennEngineering® Screw Head, Spring-loaded - Metric PFS2-M6-04-BN

PFS2™ captive panel screws are spring-loaded, tool- or hand-operated fasteners designed for secure mounting and easy removal in thin sheet materials. They feature an external thread in ASME B1.1, 2A / ASME B1.13M, 6g configuration, with a retainer and screw made of hardened carbon steel and a spring of 300 series stainless steel. A nylon retaining ring limits operation temperature to 200°F (93°C). The screw assembly remains captive during installation and removal. For M6×1 thread size, the minimum sheet thickness is 0.060 in (1.53 mm), maximum sheet thickness is 0.375 in (9.5 mm), and minimum hole size is 0.164 in (4.17 mm). The screw head height is 0.437 in (11.1 mm), and the minimum distance from hole center to panel edge is 0.34 in (8.64 mm). The series supports sheet hardness up to HRB 80 or HB 150.
