S-93945A064 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments
• Efficient thread forming technology creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time
• Secure square drive design provides maximum torque transfer and prevents cam-out during installation
• Precision 82° countersink angle ensures flush mounting and clean finished appearance in sheet metal applications
• Full threading along the 3-inch length offers maximum grip and holding power throughout the entire fastener
• Compatible with standard 3/16" drill bits for easy installation and reduced tooling requirements
• Environmentally compliant construction meets RoHS 3 and REACH standards for sustainable industrial use

Professional Applications & Engineering Value

These No. 12 thread forming screws are engineered specifically for sheet metal applications where reliable fastening is critical. The 18-8 stainless steel composition provides exceptional resistance to corrosion and oxidation, making them ideal for outdoor equipment, HVAC systems, and industrial machinery exposed to moisture or chemicals. The thread forming technology eliminates the need for separate tapping operations by cold-forming mating threads directly into the material, creating stronger thread engagement than conventional cutting screws. This design prevents metal chips and debris, maintaining clean work environments while providing vibration-resistant connections. The square drive flat head configuration ensures secure installation with standard tools, while the precise 82° countersink angle allows for seamless flush mounting in metal panels and assemblies.

Specification Summary & Compliance

These tapping screws feature No. 12 size with 3-inch length and right-hand threading, manufactured to A/AB tapping screw standards with fully threaded shank design. The precision engineering ensures consistent performance with specified 0.1875" drill bit compatibility and 0.025" maximum drilling thickness capability. All components are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, providing sustainable fastening solutions for industrial applications requiring regulatory adherence.
