Type SMPS self-clinching nuts are for installation into ultra-thin sheets. They feature a lower profile and can be mounted closer to the edge of a sheet than other self-clinching nuts.
  • Installs into sheets as thin as .025”.
  • Recommended for use in sheets HRB (Rockwell “B” scale) 70 or less and HB (Hardness Brinell) 125 or less.
Type SMPP self-clinching nuts are for installation into ultra-thin sheets.
  • Installs into stainless steel sheets as thin as .025”.
  • Corrosion resistance similar to 300 series stainless steel.
  • Reduced outer dimensions and thinner sheet capabilities compared to type SP thread sizes.
  • Recommended for use in stainless steel sheets HRB 90 / HB 192 or less.
