PEMSERT® Self-clinching Flush Fasteners.
Installs flush into stainless steel sheets

Type F4™ fasteners are ideal for flush applications where a stainless steel sheet requires loadbearing threads. The PEM® flush nut can be installed easily by squeezing it into a round hole in metal sheets. When the fastener is properly installed, both the top and the bottom of the sheet remain flat, enhancing the functional and cosmetic qualities of the entire assembly. The hexagonal head along with the proven PEM self-clinching design ensures high axial and torsional strength.
