S-93406A251 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability.
• Enhanced load distribution from the wide truss head design, reducing surface damage and preventing pull-through in thin sheet metal.
• Efficient, secure installation using the No. 2 Phillips drive, minimizing cam-out and speeding up assembly processes.
• Strong, reliable thread forming creates durable mating threads in sheet metal without pre-tapping, ensuring vibration resistance.
• Full-length threading provides maximum grip and holding power along the entire 1-1/2" length for secure fastening.
• Optimized for 0.025" maximum drilling thickness, making it perfect for standard sheet metal fabrication and HVAC applications.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets international supply chain requirements.

Professional Applications & Engineering Value

This No. 10 x 1-1/2" Phillips Truss Head Tapping Screw is engineered to solve common challenges in sheet metal assembly, such as material stripping and loosening under vibration. The 18-8 Stainless Steel offers excellent corrosion resistance, crucial for outdoor or humid environments. Its thread forming (Type A/AB) design displaces material to create strong, precise internal threads without chips, eliminating the need for cleaning and reducing installation time. The wide truss head distributes clamping force over a larger area, preventing distortion in thin-gauge metals. Ideal for HVAC ductwork, electronic enclosures, and automotive panels, this screw ensures durable, maintenance-free joints that withstand dynamic loads and thermal cycling.

Specification Summary & Compliance

This screw features a No. 10 thread diameter (0.19") with 12 threads per inch and a right-hand thread direction. The head diameter is 0.448" with a No. 2 Phillips drive for precise torque application. It is fully threaded and designed for use with a No. 21 drill bit (0.159" diameter). Manufactured to common industrial standards for thread forming tapping screws, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it is free from hazardous substances and suitable for global markets.
