S-93880A578 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Maximum holding power achieved through the integrated flange design that distributes clamping force evenly across surfaces
• Efficient thread forming action with Type B tapping design creates strong, permanent threads in sheet metal without pre-tapping
• Quick installation and removal enabled by the external hex head design that provides excellent torque transmission
• Full-length threading ensures consistent grip strength along the entire 1/2" length for reliable fastening performance
• Precise installation compatibility with standard 6.9mm drill bits reduces setup time and improves assembly accuracy
• Environmental compliance assurance with RoHS 3 certification for use in regulated applications and global markets

Professional Applications & Engineering Value

These heavy-duty tapping screws are specifically engineered to address common challenges in sheet metal fabrication and assembly operations. The zinc-plated steel construction provides essential corrosion protection while maintaining the high tensile strength required for structural applications. The thread forming design (Type B) eliminates the need for separate tapping operations by creating precise, strong threads directly in the base material, significantly reducing assembly time and labor costs. The combination of external hex drive and flanged head delivers superior torque transmission and clamping force distribution, preventing material deformation and ensuring vibration-resistant connections. These features make these 5/16"-12 TPI screws ideal for HVAC systems, electrical enclosures, automotive panels, and industrial equipment where reliable, long-lasting fastening solutions are critical.

Specification Summary & Compliance

This tapping screw features precise 0.313" thread diameter with 12 threads per inch and right-hand threading throughout its 1/2" length. The fastener meets industry standards for thread forming screws Type B and is designed for optimal performance with 6.9mm (0.2717") drill bits. The product is fully compliant with RoHS 3 (2015/863/EU) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide. The zinc-plated steel material and fully threaded blunt tip design provide consistent performance across various sheet metal thicknesses and compositions.
