S-94155A131 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in demanding industrial environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling costs.
• Secure No. 2 square drive provides excellent torque transmission and prevents cam-out during high-torque applications.
• Optimized pan head profile offers a low-profile, finished appearance while distributing clamping force effectively across surfaces.
• Full threading along the 1/2" length ensures maximum grip and holding power throughout the entire fastened material thickness.
• Precise drill compatibility with No. 21 drill bit (0.159" diameter) enables clean installations in materials up to 0.025" thickness.
• Environmental compliance assurance with RoHS 3 and REACH regulations, meeting international standards for hazardous substance restrictions.

Professional Applications & Engineering Value

These thread forming tapping screws deliver exceptional performance in sheet metal applications where vibration resistance and permanent fastening are critical. The 18-8 stainless steel composition provides excellent corrosion resistance, making these A/AB type screws ideal for HVAC systems, electrical enclosures, and automotive assemblies exposed to moisture or chemicals. The thread forming design displaces material rather than removing it, creating stronger threads that won't loosen under stress. With right-hand threads and fully threaded shanks, these industrial screws ensure maximum engagement in thin materials, while the pan head with square drive offers both aesthetic appeal and reliable installation. This combination addresses common challenges of strip-out, corrosion, and installation efficiency in metal fabrication.

Specification Summary & Compliance

These screws feature precise No. 10-12 thread specifications with 12 threads per inch and 0.19" thread diameter, manufactured to standard tolerances for consistent performance. The thread forming tapping method follows industry standards for A/AB type sheet metal screws. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures these fasteners meet current environmental standards for hazardous substance restrictions, making them suitable for global industrial applications and regulated industries.
