The SO-6440-22ZI is a through-hole threaded self-clinching standoff for installation in steel or aluminum sheets with a maximum hardness of HRB 70 or HB 125. It has a .138-32 thread, a nominal length of .213 inch, a barrel diameter of .125 inch, and requires a minimum hole size of .040 inch. The standoff is made from hardened stainless steel, installs flush with the sheet surface, and requires a minimum edge distance of .27 inch. The 6440 code indicates a thicker wall design to increase bearing surface and reduce panel damage. The minimum sheet thickness is .025 inch.
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.
PEM® brand thru-hole threaded standoffs are installed with their heads flush with one surface of the mounting sheet.
