Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliable fastening is critical. The thread forming Type A/AB design eliminates the need for pre-tapped holes, creating strong internal threads that resist vibration loosening and provide exceptional pull-out strength. The combination of No. 2 square drive and pan head configuration ensures secure installation without stripping while maintaining a low-profile finish. Ideal for HVAC systems, electrical enclosures, and metal fabrication projects, these fully threaded screws deliver consistent performance across various sheet metal thicknesses up to 0.025", making them essential for industrial assembly lines and maintenance operations requiring durable, corrosion-resistant fastening solutions.

Specification Summary & Compliance

These No. 8-15 thread forming screws feature precise Class 2A thread tolerances with 0.164" thread diameter and 15 threads per inch. The manufacturing complies with standard tapping screw specifications for Type A/AB thread forming applications. Environmental compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet the latest environmental standards for industrial use. The specified No. 29 drill bit size (0.136" diameter) provides optimal hole preparation for maximum thread engagement and holding strength in sheet metal substrates.
