These no-spring steel fasteners integrate a captive screw to keep loose parts to a minimum and eliminate the potential risk for damage to internal components associated with unsecured hardware. They offer solutions to attach thin metal sheets while enabling subsequent access to an assembly whenever necessary. Their compact and low profile design especially suits applications where space or access areas for hardware may be restricted.
Designers can additionally specify MAThread anti-cross-thread technology as a safeguard to correct off-angle thread mating and promote proper alignment during installation. A Torx recess can further be supplied instead of the standard universal slot/Phillips drive.
PEM Type PFHV captive panel screws are engineered for use with aluminium or steel sheets as thin as .036-in/0.92mm and exhibiting hardness of HRB 60 or less on the Rockwell “B” Scale or HB 107 or less on the Brinell Scale. They install easily and quickly by squeezing them into properly sized holes using a PEMSERTER press or other standard equipment to develop sufficient force. The fasteners then clinch permanently into place with the side opposite the fastener remaining flush and become an integral part of an assembly.
These captive panel screws are available in two screw lengths and with thread sizes from #4-40 through #8-32 and M3 through M4.
