PEMSERT® Self-Clinching Flush Fasteners - Type F

PEMSERT self-clinching flush nuts are designed to be completely flush in sheets as thin as 1.5mm.

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 the entire assembly. PEMSERT self-clinching flush nuts can be installed in metal sheets before bending and forming. This can provide strong threads in places which would be inaccessible for installation after chassis are formed.

The hexagonal head along with the proven PEM self-clinching design ensures high axial and torsional strength and PEMSERT Type F fasteners can be ordered to conform to US NASM45938/4 specifications.
