Professional Applications & Engineering Value
These 1/4-20 UNC Torx Plus tapping screws deliver exceptional engineering value through their specialized thread-forming design and tri-lobe shank construction. The black corrosion-resistant coated steel provides durable protection against environmental factors, making them ideal for aluminum, brass, and copper assemblies in manufacturing, electrical enclosures, and HVAC systems. The Torx Plus IP30 drive system ensures maximum torque transmission while minimizing tool slippage and fastener damage during high-torque applications. The fully threaded design with coarse UNC threading creates strong, reliable connections in soft materials without requiring pre-tapped holes, significantly reducing installation time and labor costs in industrial production environments.
Specification Summary & Compliance
These tapping screws feature precision 1/4"-20 UNC coarse threads with standard thread tolerances and tri-lobe shank cross-section for optimal performance in thread-forming applications. The fasteners maintain dimensional accuracy with length tolerance of -0.03" to 0" and are manufactured to industrial standards for consistent quality. Compliance is verified with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial and commercial applications worldwide.
