S-93406A258 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in demanding environments.
• Excellent holding power from the thread forming (Type A/AB) design, creating strong, permanent threads in sheet metal without pre-tapping.
• Enhanced load distribution thanks to the wide truss head, which provides a larger bearing surface and reduces material stress.
• Efficient, high-torque installation with the No. 2 Phillips drive, minimizing cam-out and speeding up assembly.
• Full-length threading for maximum grip along the entire 3-inch length, ideal for varying material thicknesses.
• Simplified installation process as these screws are compatible with a standard No. 21 drill bit (0.159" diameter), reducing setup time.
• Compliance with strict environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use in industrial applications.

Professional Applications & Engineering Value

These No. 10 x 3" 18-8 stainless steel Phillips truss head tapping screws are specifically engineered for sheet metal applications, where vibration resistance and pull-out strength are critical. The thread forming technology displaces material to form precise, robust internal threads, eliminating the need for separate tapping operations and reducing assembly costs. Made from durable 18-8 stainless steel, they resist rust and corrosion in harsh conditions, making them ideal for HVAC systems, electronic enclosures, and automotive assemblies. The truss head design distributes clamping force over a wider area, preventing sheet distortion and ensuring a secure, flush fit. With a No. 2 Phillips drive and fully threaded shank, these screws offer quick, reliable fastening for high-volume metalworking projects, enhancing productivity and joint integrity.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.19" and approximately 12 threads per inch, ensuring precise fit. The screws are manufactured as Type A/AB thread forming tapping screws with a right-hand thread direction and pointed tip for easy starting. They are designed for use with a No. 21 drill bit (0.159" diameter) and can handle maximum drilling thicknesses up to 0.025". Compliance is confirmed with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing they are free of hazardous substances and suitable for global industrial standards.
