PennEngineering® Threaded Standoffs for Stainless Sheets as Thin as 0.63mm TSO4-M35-1200

TSO4™ self-clinching standoffs are designed for installation into ultra-thin stainless steel sheets as thin as 0.63 mm. The TSO4-M35-1200 is a metric threaded standoff with a 3.5 mm thread size and a length of 19.00 mm, classified as Style #3 (blind). It features a minimum hole size of 6.4 mm and requires a minimum distance to edge of 7.1 mm. The part is made of heat-treated 400 series stainless steel with a passivated finish per ASTM A380. Installation requires a punch with a B dimension of 6.35-6.53 mm and a specific anvil for sheets over 0.63 mm. Pushout and torque-out performance values are based on testing in 0.64 mm thick 300 series stainless steel.
