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 loadbearingthreads. The PEM® flush nut can be installed easily by squeezing it into a round holein metal sheets. When the fastener is properly installed, both the top and the bottom of thesheet 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 andtorsional strength.
