Part # F-440-2, PEMSERT® Self-Clinching Flush Fasteners - Type F

PEMSERT self-clinching flush nuts are designed to be completely flush in sheets as thin as .060”.

These fasteners are ideal for applications where a thin sheet requires load-bearing threads but still must remain smooth, with no protrusions on either surface. The PEM flush nut can be installed easily by squeezing it into a round hole in metal sheets. When the fastener is installed, both the top and the bottom of the sheet remain smooth, enhancing the functional and cosmetic qualities of themore
