Professional Applications & Engineering Value

These zinc-plated steel tapping screws are specifically engineered for sheet metal applications where reliability and durability are paramount. The thread forming design eliminates the need for pre-tapped holes, reducing installation time and labor costs while creating strong, vibration-resistant connections. The flat head profile with 82° countersink ensures smooth, flush surfaces that won't interfere with adjacent components or create safety hazards. Made from high-strength steel with protective zinc plating, these Phillips drive screws withstand environmental exposure while maintaining their structural integrity in HVAC systems, electrical enclosures, and metal fabrication projects. The combination of No. 4-24 threading and pointed tip facilitates easy starting and precise alignment, making them ideal for high-volume assembly operations.

Specification Summary & Compliance

These thread forming tapping screws feature precision No. 4-24 UNC Class 2A threads with right-hand direction and full threading along the 1-inch length. Manufactured to A/AB tapping screw standards with standard flat head profile and compatible with No. 44 drill bit (0.086" diameter) for proper hole preparation. The screws maintain maximum drilling thickness capacity of 0.025" and are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial fastener applications.
