Self-Clinching Nuts - Types SP - Unified, specifically the part number SP-0420-0, are designed for permanent installation in stainless steel sheets as thin as 0.030 inches. These fasteners are made from specially hardened stainless steel, ensuring they are harder than the host material for reliable performance. They are suitable for applications requiring strong load-bearing internal threads and are compatible with stainless steel sheets with a hardness of HRB 90 or less and HB 192 or less. The corrosion resistance of these nuts is comparable to that of 300 series stainless steel, making them ideal for environments exposed to corrosive elements. Proper installation techniques are crucial to avoid issues such as thread binding, particularly in stainless steel applications.
Type SP, PEM 300® nuts provide strong load-bearing threads in stainless steel sheets as thin as .030”.
Type SP is recommended for use in steel or aluminum sheets HRB (Rockwell “B” scale) 90 or less and HB (Hardness Brinell) 185 or less.
For SP type products that have a “single ring” marking on the barrel, please refer to PEM® bulletin CL for installation information.
