PennEngineering® Threaded Standoffs for Stainless Sheets as Thin as 0.63mm TSO4-M35-1800

TSO4™ self-clinching standoffs are designed for installation into ultra-thin stainless steel sheets as thin as 0.63 mm. The TSO4-M35-1800 variant, part of the TSO4 series, features an M3.5 x 0.6 internal thread and a length of 19.00 mm, corresponding to Style #3. It is manufactured from heat-treated 400 series stainless steel with a passivated finish per ASTM A380, and is rated for use in materials with a hardness of HRB 88 or HB 183 or less. The part requires a minimum hole size of 6.4 mm and a minimum edge distance of 7.1 mm. Installation requires a flush embedment using specific anvil and punch tooling designed for sheet thicknesses under 0.81 mm. The series is qualified for metric threading per ASME B1.13M, 6H.
