PennEngineering® Threaded Standoffs for Stainless Sheets as Thin as .025” TSO4-256-625

TSO4-256-625 is a self-clinching standoff designed for installation into ultra-thin stainless steel sheets as thin as 0.025 in. (0.63 mm). It features a .090-56 thread, a length of 0.625 in. (15.88 mm), and an oversized body for increased bearing surface and performance. The standoff is made of heat-treated 400 series stainless steel with a passivated finish per ASTM A380, and is rated for use in materials with hardness HRB 88 or HB 183 or less. Installation requires a properly sized hole and specific anvil tooling (Part No. 8003292) for sheet thicknesses up to 0.032 in. (0.81 mm). Pullout force averages 6800 lbf (30.3 kN) and torque-out resistance averages 22 in.-lb (2.5 N·m) when installed correctly.
