PennEngineering® Threaded Standoffs for Stainless Sheets as Thin as 0.63mm TSO4-6M3-600

TSO4™ self-clinching standoffs are designed for installation into ultra-thin stainless steel sheets as thin as 0.63 mm. The TSO4-6M3-600 is a metric threaded standoff with a 6M3 thread, a length of 6.00 mm, and an oversized body for increased bearing surface and wall thickness. It has a minimum hole size of 6.4 mm and requires a minimum edge distance of 7.1 mm. The standoff is made from heat-treated 400 series stainless steel with a passivated finish per ASTM A380 and is rated for use in materials with hardness up to HRB 88 or HB 183. Installation requires a punch and anvil with specific dimensions: 6.35-6.53 mm for the anvil bore. Performance data shows an average pushout force of 30.3 kN and a torque-out resistance of 2.5 N·m when installed in 0.64 mm 300 series stainless steel.
