SO-440-22ZI is a through-hole threaded self-clinching standoff designed for installation in steel or aluminum sheets with a hardness of HRB 80 or less. It has a #4-40 thread, a nominal length of 0.687 inches (22 in 32nds of an inch), and installs in a minimum hole size of 0.040 inches. The standoff has a barrel diameter of 0.166 inches and requires a minimum distance of 0.187 inches from the hole centerline to the sheet edge. The ZI suffix indicates an optional nickel plating for corrosion resistance. The part forms a flush, permanent mount into sheets as thin as 0.025 inches.
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.
