PennEngineering® Threaded Standoffs for Stainless Sheets as Thin as .025” TSO4-440-125

The TSO4-440-125 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 unified thread size of #4-40 and a length of 1.25 inches. It is made from heat-treated 400 series stainless steel and is passivated or tested per ASTM A380, ensuring durability and corrosion resistance. The standoff is engineered for easy installation, requiring a properly sized mounting hole without any secondary operations like deburring. It is compatible with specific installation tooling, including designated punches and anvils for sheets below .032 inches in thickness. Performance data indicates high pushout and torque-out resistance, making it suitable for applications where secure fastening is critical. Engineers should consider this standoff for projects requiring reliable fastening solutions in thin stainless steel materials.
