Professional Applications & Engineering Value

These No. 8 thread forming tapping screws deliver exceptional performance in sheet metal fabrication and assembly operations. The Black-Oxide Steel construction provides superior corrosion protection, while the thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs. The fully threaded configuration ensures maximum holding power across the entire fastener length, making them ideal for securing thin-gauge materials where pull-out resistance is critical. The oval head profile with standard countersink angle creates a smooth, finished appearance while maintaining structural integrity. Engineered for industrial durability, these screws withstand vibration and mechanical stress in demanding applications from electrical enclosures to HVAC systems and automotive components.

Specification Summary & Compliance

These precision-engineered tapping screws feature a 0.164" thread diameter with 15 TPI precision threading and right-hand thread direction. The No. 8 screw size with 3/4" length provides optimal fastening capacity for standard sheet metal thicknesses. Manufactured to A/AB tapping screw standards with Class 2A thread tolerances, these fasteners ensure consistent performance and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting the latest industrial standards for safe and sustainable manufacturing practices.
