Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional engineering value through their thread-forming UNC coarse thread design, specifically engineered to eliminate common installation challenges in industrial assembly. The SW tapping screw type creates precise, durable threads in steel, aluminum, brass, and cast iron without requiring pre-tapped holes, significantly reducing assembly time and labor costs. The Phillips No. 2 drive ensures reliable torque transmission while minimizing tool slippage, making them ideal for high-volume production environments. With full threading and 0.138" thread diameter, these screws provide maximum engagement depth and superior pull-out resistance in sheet metal applications, electrical enclosures, machinery components, and automotive assemblies where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

These industrial-grade fasteners feature Class 2A thread tolerances with UNC coarse thread specifications (6-32 thread size) and 3/4" length precision manufacturing. The thread-forming tapping method (SW type) complies with industry standards for self-tapping applications in various metals. Regulatory compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring they meet the latest international restrictions on hazardous substances for industrial and commercial use.
