PennEngineering® Threaded Standoffs for Stainless Sheets as Thin as 0.63mm TSO4-M35-300

TSO4™ self-clinching standoffs are designed for installation into ultra-thin stainless steel sheets as thin as 0.63 mm. The TSO4-M35-300 is a metric thread variant with M3.5 x 0.6 internal threads, 3.00 mm length, and Style #1 configuration - fully threaded through. It is manufactured from heat-treated 400 series stainless steel with a passivated finish per ASTM A380, and is rated for use in sheet materials with hardness not exceeding HRB 88 or HB 183. The minimum hole size for installation is 4.8 mm, with a minimum distance to edge of 7.1 mm. Pushout force averages 6800 lbs (30.3 kN) and torque-out value averages 22 in. lbs (2.5 N•m) when installed in 0.64 mm 300 series stainless steel. Installation requires a punch and anvil with parallel surfaces and a chamfered anvil only for sheets below 0.81 mm.
