Original Press Release

New PEMSERT® Type F4(TM) Self-Clinching Flush Nuts Install Into Stainless Steel Sheets Without Creating Any Protrusions

Press release date: July 2, 2014

New PEMSERT® Type F4™self-clinching flush nuts from PennEngineering® introduce ideal attachment solutions for stainless steel assemblies by providing load-bearing threads in thin stainless sheets without creating any protrusions on either side.  Upon their permanent installation into 300 Series stainless steel sheets as thin as .060” / 1.53mm, both the top and bottom of the sheet will remain flat for enhanced functional and/or cosmetic qualities of an entire assembly.  These nuts additionally can help deliver production efficiencies down the line by installing flush before sheet bending or forming operations get under way and eliminating any risk of interference associated with protruding hardware.

Installation is accomplished easily by squeezing the nut into a round hole in a stainless sheet using sufficient force to embed the nut’s hexagonal head flush in the sheet.  The metal displaced by the head then flows evenly around the back-tapered shank of the fastener to securely lock the nut permanently into place.  Both the hexagonal head and the fastener’s self-clinching design ultimately combine to deliver high pullout and torque out resistances.  Only a single mating screw is required to complete the attachment process.

PEMSERT Type F4 self-clinching flush nuts are manufactured from 400 Series stainless steel in thread sizes #2-56 through ¼-20 / M2 through M6.  They can perform as intended in stainless steel sheets with hardness up to HRB 88 on the Rockwell “B” scale or HB 183 on the Brinell scale.
