A new patented PEM self-clinching stainless-steel panel fastener is the first designed to install “flush” (on one side) into thin stainless-steel sheets. This new PEM Type PFC4 panel fastener (400 Series stainless steel) can be installed permanently in stainless sheets up to HRB 88 hardness on the Rockwell “B” scale and meets UL1950 “service area access” requirements to enable subsequent access to an assembly. The side of the sheet opposite installation remains flush. Ideal for attaching stainless sheets as thin as 1.53mm and for applications requiring high corrosion resistance, PEM Type PFC4 self-clinching panel fasteners feature a captive-screw design to keep hardware to a minimum, promote quick installation, and eliminate any risk of loose parts falling out and damaging components. A Phillips recess is standard.
PEM Type PFC4 self-clinching panel fasteners (complete spring-loaded assemblies) are available in assorted screw lengths and in thread sizes 4-40 through 10-32 and M3 through M5. Installation (using a Pemserter or other 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. Installation is completed by applying a squeezing force until the shoulder of the retainer comes in contact with the sheet material. There will be no protrusions on the side of the sheet opposite installation.
