Access hardware is self-clinching

Self-clinching access hardware incorporates a captive screw in a spring-loaded assembly to keep parts to a minimum and prevent screws from falling out and damaging internal components.
PEM Type PF50/60 self-clinching access hardware incorporates a captive screw in a spring-loaded assembly to keep parts to a minimum and prevent screws from falling out and damaging internal components.
These panel fastener assemblies subsequently allow for quick and easy access to components whenever necessary.
The hardware meets UL508 "operator access area" requirements (Type PF50) and UL1950 "service access area" requirements (Type PF60).
Both types are RoHS compliant.
Their low-profile design keeps protrusion on front panels to a minimum.
When tightened, the fastener (depending on size) will protrude as little as .340"/8.64mm from the top of the sheet.
This further serves to enhance front-panel appearance.
PEM PF50/60 steel panel fastener assemblies incorporate a Phillips recess to enable their captive screws to be tightened or loosened simply using a Phillips screwdriver.
Their large heads (knurled or smooth knobs, depending on type) further provide for operation by hand without tools.
PEM Type PF50/60 self-clinching access hardware installs permanently in aluminium or steel panels as thin as .030"/0.8mm.
The assemblies are offered in multiple screw lengths with thread sizes ranging from 4-40 through 1Z4-20 and M3 through M6.
Customisation options include a six-lobe recess and scratch-proof DuraBlack finish.
These types of access hardware join a complete family of PEM panel fastener solutions for thin-material assemblies.
