PFK™ broaching captive panel screws are designed for permanent installation in printed circuit boards, featuring a 0.138-32 (#6-32) thread, stainless steel screw and spring, and a nylon retaining ring rated to 200°F (93°C). The screw shank length is 0.250 in, with a minimum sheet thickness of 0.060 in and a minimum hole size of 0.281 in. The installed height above the sheet is 0.072 in, and the minimum distance from the hole centerline to the edge is 0.260 in. The retainer and screw are passivated per ASTM A380. The diagonal knurl identifies metric thread sizes, and the part includes a shoulder stop for controlled installation.
