S-93406A202 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and extended service life in industrial settings.
• Enhanced load distribution and reduced surface pressure due to the wide truss head design, preventing material damage in sheet metal applications.
• Secure, reliable fastening without pre-drilled holes using thread forming technology, which creates strong threads and resists loosening under vibration.
• Efficient installation with a No. 2 Phillips drive, providing good torque transfer and reducing the risk of cam-out during assembly.
• Full threading for maximum grip length, ensuring consistent holding power along the entire 3/4" length in sheet metal up to 0.025" thickness.
• Compliance with RoHS 3 and REACH regulations, ensuring safety and environmental standards are met for global industrial use.
• Precision-engineered right-hand threads with 15 threads per inch for optimal engagement and pull-out strength in metal fastening.

Professional Applications & Engineering Value

This 316 stainless steel tapping screw is engineered to address common challenges in sheet metal fabrication, such as corrosion from exposure to moisture, chemicals, or outdoor elements. The thread forming design eliminates the need for tapping operations, as it cold-forms mating threads in the material, reducing installation time and providing superior resistance to vibration loosening compared to traditional screws. The wide truss head offers a larger bearing surface, distributing clamp load effectively to prevent sheet metal distortion or cracking. Ideal for HVAC systems, electrical enclosures, and automotive assemblies, this screw ensures durable, maintenance-free fastening in demanding industrial applications, backed by its high-strength No. 8 size and precise Phillips drive for consistent performance.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a thread diameter of 0.164" and length of 3/4", featuring fully threaded right-hand threads at approximately 15 threads per inch for reliable engagement. It conforms to common industrial standards for thread forming tapping screws (Type A/AB), ensuring dimensional accuracy and performance in sheet metal. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting strict environmental and safety regulations for hazardous substances.
