• Optimized for soft materials with UNC coarse threading providing excellent pull-out resistance in non-ferrous metals
• Precision dimensional control with length tolerance of -0.03" to 0" ensuring consistent installation depth and performance
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial applications
• Complete threading coverage with fully threaded blunt tip design for maximum engagement strength in thin materials

Professional Applications & Engineering Value

These 2-56 UNC Tri-Lobe tapping screws deliver exceptional engineering value in aluminum, brass, and copper applications where traditional fastening methods may fail. The black corrosion-resistant coated steel construction provides vital protection against environmental degradation, while the Torx Plus IP7 drive system ensures maximum torque transfer without stripping, significantly reducing installation time and tool replacement costs. The innovative Tri-Lobe shank cross-section displaces material during installation to form permanent, high-strength threads that resist vibration loosening and maintain clamping force in soft non-ferrous metals. This combination of thread forming technology and premium surface treatment makes these screws ideal for electronics enclosures, HVAC components, and precision machinery where reliable fastening in lightweight materials is critical.
