S-91655A201 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in harsh industrial environments.
• Effortless installation thanks to the thread-forming design and pointed tip, reducing assembly time and tool wear.
• Enhanced grip and stability from the flanged pan head, which distributes load evenly and prevents pull-through in sheet metal.
• Secure, non-slip fastening with the No. 2 square drive, providing reliable torque transfer and minimizing cam-out risks.
• Full-thread engagement for maximum holding power in materials up to 0.025" thickness, ideal for precision sheet metal work.
• Wide compatibility with standard No. 29 drill bits, streamlining your drilling and fastening processes.
• Cost-effective reliability through A/AB thread standards, ensuring consistent performance in repetitive manufacturing tasks.

Professional Applications & Engineering Value

These No. 8-15 thread forming tapping screws are engineered to address common challenges in sheet metal applications, such as material cracking and loose fasteners. Made from zinc-plated steel, they resist rust and corrosion, extending service life in demanding settings like HVAC, automotive assemblies, and construction frameworks. The thread forming design creates strong, precise threads without cutting, which minimizes debris and enhances joint integrity. Combined with a flanged pan head and No. 2 square drive, these screws ensure quick, secure installations, reducing labor costs and improving overall assembly efficiency for industrial professionals.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.164" and 15 threads per inch, ensuring precise fit in accordance with common tapping screw specifications. It meets typical industry standards for thread forming and A/AB tapping screw types, with a right-hand thread direction for universal compatibility. Manufactured to deliver reliable performance in materials up to 0.025" thickness using a No. 29 drill bit, these screws support compliance with general industrial fastening norms, though specific certifications like RoHS or REACH should be verified per batch for environmental and safety adherence.
