PennEngineering® Threaded Standoffs for Stainless Sheets as Thin as 0.63mm TSO4-6M25-1900

TSO4-6M25-1900 is a self-clinching standoff for installation into ultra-thin stainless steel sheets as thin as 0.63 mm. It features a metric M2.5x0.45 thread with an overall length of 19.00 mm and an oversized body for increased bearing surface and wall thickness. The standoff is made of heat-treated 400 series stainless steel with a passivated finish compliant with ASTM A380. It is designed for use in materials with hardness HRB 88 or HB 183 or less and meets ASME B1.1 2B and ASME B1.13M 6H thread standards. The part requires a minimum hole size of 6.4 mm, a minimum hole depth of 7.1 mm, and a minimum distance to edge of 7.1 mm for proper installation. Installation requires a punch and anvil set with the specified geometry for sheets under 0.81 mm thickness.
