Professional Applications & Engineering Value
These No. 8 x 3" zinc-plated steel tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming design eliminates the need for pre-tapped holes, reducing installation time and labor costs while creating stronger, more reliable threads in the parent material. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the dual Phillips/Slotted drive options ensure compatibility with various installation tools. With a maximum drilling thickness of 0.025", these A/AB type tapping screws are engineered to handle standard gauge sheet metal applications efficiently, making them ideal for HVAC systems, electrical enclosures, and metal furniture assembly where vibration resistance and long-term reliability are critical.
Specification Summary & Compliance
These tapping screws feature precise 0.164" thread diameter with 15 threads per inch and standard Class 2A thread tolerances for consistent performance. The pan head design measures 0.322" in diameter with 0.115" height, accommodating standard driving tools with No. 2 drive size. Manufactured to A/AB tapping screw specifications with right-hand threading and fully threaded shank design. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global manufacturing applications.
