Professional Applications & Engineering Value

This heavy-duty tapping screw delivers exceptional engineering value in metal fabrication and assembly operations. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength for structural applications. The thread cutting design (Type F) eliminates the need for pre-tapped holes, significantly reducing installation time and labor costs in aluminum, brass, cast iron, and sheet metal components. The combination of UNC coarse threading and serrated flange ensures vibration-resistant fastening that maintains clamp load in high-stress environments. The external hex drive facilitates efficient installation with standard tools, making it ideal for production lines and field service applications where reliability and speed are critical.

Specification Summary & Compliance

This 1/2"-13 UNC coarse thread tapping screw features Class 2A thread tolerances and complies with ASME B18.6.3 dimensional standards SAE J933. The fastener is RoHS 3 (2015/863/EU) Compliant and manufactured to precise specifications including a 1-1/2" length, 3/4" hex head width, and 1.04" flange diameter. The thread cutting (Type F) design is engineered for use with 29/64" (0.4531") drill bits, ensuring proper hole preparation for optimal thread formation and holding strength in various metal substrates.
