SO-6440-4ZI is a through-hole threaded self-clinching standoff designed for installation in steel or aluminum sheets with a Rockwell B hardness of 70 or less or Brinell hardness of 125 or less, featuring a thicker wall for enhanced bearing surface. It has a .040 inch minimum hole size, a nominal thread of .138-32, and a head diameter of .125 inch. The standoff is installed with the head flush to the sheet surface and is available in lengths up to .187 inch. The ZI suffix indicates nickel plating for corrosion resistance.
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.
If you require a standoff which we do not offer in this bulletin, please contact us. We will be happy to work with you to satisfy your special need.
