This listing is for twenty five nuts. 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.
