Professional Applications & Engineering Value

These No. 6 x 1/2" zinc-plated steel tapping screws deliver exceptional engineering value in sheet metal fabrication and assembly operations. The thread forming design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs while creating stronger, more reliable threads that resist vibration loosening. The A/AB tapping screw type with right-hand threading ensures consistent performance across various sheet metal thicknesses up to 0.025". The combination of zinc-plated steel material and fully threaded construction provides superior corrosion resistance and maximum pull-out strength, making these industrial screws ideal for HVAC systems, electrical enclosures, automotive components, and machinery assemblies where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

These tapping screws feature precise 0.138" thread diameter with 18 threads per inch and Class 2A thread tolerances for consistent fit and performance. The pan head style measures 0.27" in diameter with 0.097" height, providing optimal clamping force distribution. Manufactured to industry standards for sheet metal fasteners, these screws are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The thread forming tapping method creates secure, permanent fastenings without requiring pre-tapped holes, streamlining assembly processes while maintaining structural integrity.
