Professional Applications & Engineering Value

These No. 6-18 x 1" zinc-plated steel tapping screws deliver exceptional engineering value in sheet metal applications where traditional fastening methods fall short. The thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating stronger, more reliable threads that resist vibration loosening. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the pointed tip and precise 0.138" thread diameter ensure quick starts and smooth penetration. These A/AB tapping screws are engineered specifically for joining sheet metal components in HVAC systems, electrical enclosures, automotive assemblies, and machinery fabrication where durable, corrosion-resistant fastening is critical for long-term performance.

Specification Summary & Compliance

These thread forming sheet metal screws feature precise No. 6-18 thread specifications with 0.138" thread diameter and 18 threads per inch for consistent performance. The manufacturing adheres to standard tapping screw classifications including A/AB type for optimal thread engagement. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures these fasteners meet current industry standards for restricted substances and chemical safety. The pan head design with No. 1 square drive provides reliable torque transmission, while the 1" length and fully threaded construction deliver maximum fastening capability in sheet metal applications up to the specified thickness limits.
