The SO-440-12ZI is a through-hole threaded self-clinching standoff designed for installation in steel or aluminum sheets with a Rockwell B hardness of 80 or less, or Brinell hardness of 150 or less. It features a 0.040-inch minimum hole size, a 0.125-inch nominal thread length, and a 0.166-inch overall height. The part installs flush with the sheet surface and provides a permanent thread for mounting. The ZI suffix indicates a nickel plating option for corrosion resistance. The standoff is made from hardened stainless steel, suitable for clinching into harder base materials. Its head remains flush after installation, ensuring a smooth, flat mounting surface.
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.
