PennEngineering® Threaded Standoffs for Stainless Sheets as Thin as 0.63mm TSO4-M3-200

TSO4™ self-clinching standoffs are designed for installation into ultra-thin stainless steel sheets as thin as 0.63 mm. The TSO4-M3-200 is a metric-threaded standoff with a 3.00 mm length, internally threaded to ASME B1.13M, 6H standard, constructed of heat-treated 400 series stainless steel with a passivated finish per ASTM A380. It has a minimum hole size of 4.22 mm and requires a minimum sheet thickness of 0.63 mm. The standoff achieves a pushout force of 6800 lbs (30.3 kN) and a torque-out resistance of 22 in-lbs (2.5 N•m) when installed in 0.64 mm 300 series stainless steel, per performance test data. The part features a single groove identifier and is installed using compatible PEM® tooling with a 120° punch and specified anvil for sheets under 0.81 mm thickness.
