TSO-series self-clinching threaded standoffs are designed for installation in sheets as thin as 0.025 in (0.63 mm), providing permanent internal threads. The TSO-440 variant has a 0.040 in (1.02 mm) minimum hole size, a 0.125 in (3.18 mm) nominal thread length, and a 0.187 in (4.75 mm) minimum distance to edge. The part installs into steel or aluminum sheets with a Rockwell B hardness of 80 or less. The ZI suffix indicates nickel plating for corrosion resistance. This series offers through-hole mounting with a closed-end barrel for flush appearance.
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.
Types TSO, TSOS, and TSOA self-clinching threaded standoffs provide permanent threads in sheets as thin as .025”.
