Professional Applications & Engineering Value
These zinc-plated steel tapping screws deliver exceptional value in sheet metal applications where reliable fastening is critical. The thread forming technology eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs. The A/AB screw type with pointed tip design ensures easy starting and smooth penetration into materials up to 0.025" thickness. The Phillips pan head configuration provides excellent drive stability while the rounded profile minimizes snagging in automated assembly processes. Engineered for industrial tapping screw applications, these fasteners maintain consistent clamping force even under vibration, making them ideal for HVAC systems, electrical enclosures, and metal fabrication projects where joint integrity is paramount.
Specification Summary & Compliance
Precision manufactured to exacting standards with 0.138" thread diameter and 18 threads per inch specifications. Features right-hand threading with fully threaded design for maximum engagement. Compatible with No. 32 drill bit (0.116" diameter) for optimal hole preparation. These thread forming sheet metal screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest international compliance standards for industrial use.
