Captive panel screw installs permanently
1 min read
A self-clinching captive panel screw introduces fastener solutions engineered to install permanently and reliably into stainless steel assemblies. These components can be specified for use in stainless sheets as thin as 1.53mm with hardness up to HRB 88 on the Rockwell B scale.
The PEM Type PFC4 is an integrated captive screw in a spring-loaded assembly, which reduces loose hardware and minimises parts count; fully recessed heads in fastened position allow tool-only access; and the fasteners comply with UL 60950 access standards.
Designers can additionally specify an anti-cross thread technology as a safeguard to correct potential off-angle thread mating and promote proper alignment during installation.
The fasteners are manufactured from 400 Series stainless steel offering corrosion resistance comparable to zinc plated steel. They are available in assorted screw lengths and in thread sizes M3 to M5. All Type PFC4 captive panel screws are RoHS compliant.
Installation with a standard press is accomplished by inserting the fastener into a properly sized punched or drilled hole, placing the fastener into the hole of the anvil, and positioning the mounting hole over the fastener's shank. Sufficient squeezing force is then applied until the shoulder of the retainer comes in contact with the sheet material. The fastener ultimately will be flush on the side of the sheet opposite installation to enhance cosmetics.
