SO4™ thru-hole threaded standoffs are self-clinching fasteners designed for installation into stainless steel sheets as thin as 0.040" with a hardness of HRB 88 / HB 183 or less. They provide internally threaded, flush-mounted spacers for stacking or spacing applications, with the head flush on one surface of the sheet and the threaded bore extending through. Installed in standard round holes, they remain permanently fixed after clinching. The series supports thread sizes including .138-32 and M3, with available lengths ranging from 0.125" to 1.062". All variants feature a clinching profile designed for stainless steel and maintain corrosion resistance similar to 300-series stainless steel.
These standoffs, which use the proven self-clinching design, install with a squeeze in properly sized round holes - and become permanently mounted in the thin sheet.
Types SO4 standoffs are for installation into stainless steel sheets as thin as .040”.
