PennEngineering® Threaded Standoffs for Stainless Sheets as Thin as .025” TSO4-632-312

TSO4-632-312 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 #6-32 thread, a length of 0.312 in., and a body designed for increased bearing surface and wall thickness. The standoff is made from heat-treated 400 series stainless steel with a passivated finish per ASTM A380. It requires a minimum hole size of 0.166 in. and a minimum edge distance of 0.250 in. for proper installation. Installation uses a 120° punch and anvil, with required anvil dimensions of 0.250 in. to 0.257 in. for sheet thicknesses below 0.032 in. The pushout resistance is 6800 lbs. (30.3 kN) and torque-out resistance is 22 in.-lbs. (2.5 N•m) when installed in 0.025 in. 300 series stainless steel.
