PRODUCTS New self-clinching flush nuts PennEngineering says its new PEMSERT® P Type F4™


self-clinching flush nuts are ideal attachment solutions for stainless steel assemblies.


EMSERT® Type F4™ self-clinching flush nuts provide 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 0.06 inches/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 – 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 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. Detailed specifications,


installation animation, CAD models, and performance data (Bulletin F4) for these RoHS-compliant fasteners can be accessed online.
