SO4™ thru-hole threaded standoffs are self-clinching fasteners designed for installation into stainless steel sheets as thin as 0.040" and HRB 88 / HB 183 or less, providing internally threaded spacers for stacking or spacing applications. The SO4-440 variant features a thread size of #4-40, a shank diameter of 0.166", a recommended hole size of 0.165", and a minimum sheet thickness of 0.040". The standoff length is 0.500" (16 in 32nds of an inch), with a head height of 0.230" and a minimum distance to edge of 0.230". Installed with the head flush to one surface, it offers a counterbore diameter of 0.125" and a thread depth of 0.250". Clinching profile and groove location may vary. Installation requires careful consideration of stainless steel hardness; refer to "Dos and Don'ts" on page 27.
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”.
