PennEngineering® Threaded Standoffs for Stainless Sheets as Thin as 0.63mm TSO4-M25-300

TSO4™ self-clinching standoffs are designed for installation into ultra-thin stainless steel sheets as thin as 0.63 mm. The TSO4-M25-300 variant is a thru-threaded standoff with an M2.5 x 0.45 thread and a length of 3.00 mm. It 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 HRB 88 or HB 183 or less. The standoff requires a minimum hole size of 4.22 mm and provides a minimum edge distance of 5.4 mm. Installation requires an anvil with a bore of 4.75 to 4.93 mm for sheet thicknesses below 0.63 mm. Performance data shows a minimum 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.
