SOA-6440-20 is a through-hole threaded self-clinching standoff designed for aluminum sheets with a Rockwell B hardness of 50 or less and a Brinell hardness of 82 or less. The part features a .138-32 thread, a .281 in nominal length, and a minimum hole size of .050 in. It has a minimum distance to edge of .31 in and a head diameter of .312 in. The 6440 thread code indicates a thicker wall for improved bearing surface, reducing the risk of damage to the mating panel. The standoff installs with its head flush to one surface of the sheet and is made from hardened stainless steel, suitable for clinching into aluminum. The 20 length code corresponds to 0.625 in or 16 in the 32nds-of-an-inch length designation. Non-nickel plated finish is standard unless otherwise specified.
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.
