PennEngineering® Threaded Standoffs for Stainless Sheets as Thin as 0.63mm TSO4-6M3-800

TSO4™ self-clinching standoffs are designed for installation into ultra-thin stainless steel sheets as thin as 0.63 mm. The TSO4-6M3 variant features a metric M3 x 0.5 internal thread with a body length of 8.00 mm, an oversized body for increased bearing surface and wall thickness, and is made of heat-treated 400 series stainless steel with a passivated finish. It requires a minimum hole size of 6.4 mm and a minimum edge distance of 7.1 mm. Installation is performed using a press with a parallel punch and anvil, with recommended anvil dimensions of 6.35-6.53 mm for sheets below 0.63 mm thickness. Performance data shows a minimum pushout resistance of 6800 lbf (30.3 kN) and a torque-out resistance of 22 in-lbf (2.5 N⋅m) when installed in 0.025″/0.64 mm 300 series stainless steel.
