Captive panel screws allow simplified access to components
PennEngineering® offers PEM® types PF50™ and PF60™ self-clinching captive panel screws. They integrate a captive screw in a spring-loaded assembly to help simplify handling and installation. Their permanent mounting in thin metal assemblies helps eliminate loose hardware that can fall out and potentially cause damage to internal components.
Suitable for panels, covers, drawers, and racks, they feature a low-profile design that minimizes protrusion on front panels. When tightened, the fasteners (depending on size) protrude 0.340 in. from the top of the sheet.
The screws feature a Phillips recess as standard; a Torx® recess can be specified. Their large heads (knurled or smooth knobs, depending on type) allow for operation by hand without tools.
The steel fasteners install permanently in aluminum or steel panels as thin as 0.030 in. and are offered in multiple screw lengths with thread sizes from #4-40 through ¼-20 and M3 through M6.
