PennEngineering® Threaded Standoffs for Stainless Sheets as Thin as 0.63mm TSO4-M25-1000

TSO4™ self-clinching standoffs are designed for installation into ultra-thin stainless steel sheets as thin as 0.63 mm. The TSO4-M25-1000 is a thru-threaded standoff with an M2.5 x 0.45 thread and a 10.00 mm length. It is made of heat-treated 400 series stainless steel, passivated per ASTM A380, and rated for sheet materials with hardness HRB 88 or HB 183 or less. Minimum hole size is 4.22 mm, with a clearance hole of 6.4 mm. Installation requires an anvil with a B dimension of 4.75-4.93 mm for sheets below 0.63 mm. Performance data shows a pushout resistance of 30.3 kN and a torque-out resistance of 2.5 N·m in 0.64 mm 300 series stainless steel. The part complies with ASME B1.1 (2B) and ASME B1.13M (6H) thread standards and features a single groove identifier.
