S-94155A115 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 harsh industrial environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without chips, reducing installation time and improving joint integrity.
• Secure square drive (No. 2) provides high torque transmission and prevents cam-out, enabling reliable fastening in tight spaces.
• Fully threaded shank maximizes grip length and holding power across the entire 1/2" length for enhanced load distribution.
• Optimized pan head profile offers a low-profile, rounded finish that sits flush while distributing clamping force evenly.
• Precision-matched drill bit compatibility (No. 29 / 0.136" diameter) ensures clean hole preparation and reduces material stress during installation.
• Compliance with global environmental standards including RoHS 3 and REACH, supporting sustainable and safe manufacturing practices.

Professional Applications & Engineering Value

These thread forming tapping screws are engineered specifically for sheet metal applications, where traditional fasteners may strip or loosen under vibration. The 18-8 stainless steel material provides excellent resistance to oxidation and chemical exposure, making these screws ideal for outdoor equipment, HVAC systems, and electronic enclosures. The thread forming tapping method (Type A/AB) displaces material rather than cutting it, resulting in zero swarf and stronger thread engagement that withstands dynamic loads. With a pointed tip and fully threaded design, installation is quick and secure, reducing assembly time while maintaining high clamping force in materials up to 0.025" thickness. This combination of durability, ease of use, and precision engineering delivers reliable performance in demanding industrial fastening scenarios.

Specification Summary & Compliance

This No. 8-15 x 1/2" tapping screw features a 0.164" thread diameter with approximately 15 threads per inch, conforming to standard inch-series tolerances for consistent fit. The pan head design includes a No. 2 square drive for secure tool engagement, while the fully threaded shank ensures uniform load distribution. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, these screws meet stringent environmental and safety standards for industrial use. Recommended for use with a No. 29 drill bit (0.136" diameter) in sheet metal applications up to 0.025" thickness.
