PennEngineering® Thru-hole Threaded Standoffs - Types SO, SOA, SOS - Unified SO-632-16ZI

SO-632-16ZI is a through-hole threaded self-clinching standoff designed for installation into steel or aluminum sheets with a Rockwell B hardness of 70 or less, or Brinell hardness of 125 or less. It has a #6-32 thread, a 0.164 in nominal thread length, and a minimum hole size of 0.040 in. The standoff installs with its head flush to the sheet surface and is suitable for applications requiring permanent mounting in thin sheets as narrow as 0.025 in. The part belongs to the SO family, which provides standard-length increments up to 1.062 in. Physical dimensions, including head diameter and barrel length, align with the SO632 series data. The ZI suffix likely indicates a special finish or packaging, not a built-in performance difference from the base SO632 model.
