PennEngineering® Threaded Standoffs for Stainless Sheets as Thin as .025” TSO4-6440-500

The TSO4-6440-500 is a self-clinching standoff designed for installation in ultra-thin stainless steel sheets with a minimum thickness of .025 inches (0.63 mm). This product features a single groove identifier and is made from heat-treated 400 series stainless steel, ensuring durability and strength. The standoff is passivated and/or tested per ASTM A380, making it suitable for use in applications with a hardness of HRB 88 or HB 183 or less. The standoff has a thread size of #4-40 and is available in various lengths, allowing for customization based on project requirements. Installation requires a properly sized mounting hole, and the standoff is embedded flush into the sheet using a specific installation punch and anvil. Performance data indicates that the standoff can withstand significant pushout and torque-out forces, making it reliable for securing components in thin sheet applications. Engineers considering this product should evaluate its compatibility with their specific application needs, particularly in terms of sheet thickness and required strength.
