On permanent installation into stainless steel sheets as thin as 1.53mm, both the top and bottom of the sheet will remain flat for enhanced functional and/or cosmetic qualities of the assembly.
These nuts additionally can help deliver production efficiencies by installing flush before sheet bending or forming operations get under way, thus 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.
The 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.
