• Precision dimensional control with a length tolerance of -0.03" to 0", ensuring consistent fit and reducing assembly errors.
• Broad material compatibility for use in non-ferrous metals like aluminum, brass, and copper, minimizing the need for multiple fastener types.
• Full threading and blunt tip for easy starting and complete engagement, speeding up assembly processes.
• Compliance with global standards including RoHS 3 and REACH, supporting sustainable and safe manufacturing practices.

Professional Applications & Engineering Value

These 2-56 UNC Tri-Lobe tapping screws are engineered to address common challenges in fastening aluminum, brass, and copper components, where traditional screws may strip threads or require pre-tapping. The thread-forming Tri-Lobe shank design displaces material to create strong, permanent threads without chips, reducing the risk of loosening under vibration. Made from zinc-plated steel, they offer excellent corrosion resistance, extending service life in humid or outdoor settings. The Torx Plus IP7 drive enables higher torque application with minimal slippage, ideal for automated assembly lines and precision tools. By integrating these screws, industries can achieve faster installation, lower rejection rates, and enhanced reliability in electronics, HVAC, and machinery assemblies.

Specification Summary & Compliance
