S-93406A146 Length 3/8" 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 due to the wide truss head design, reducing the risk of material damage in sheet metal applications.
• Efficient thread forming with Type A/AB tapping, creating strong, reliable threads without pre-tapping for faster assembly.
• Secure and stable fastening from the fully threaded, pointed tip design, ensuring maximum grip and pull-out resistance.
• Optimized for sheet metal up to 0.025" thickness, paired with a No. 32 drill bit for precise, clean installations.
• Comfortable and reliable driving with a No. 2 Phillips drive, minimizing cam-out and improving torque application.
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use in regulated industries.

Professional Applications & Engineering Value

This No. 6 x 3/8" Phillips Truss Head Tapping Screw is engineered to address common challenges in sheet metal fabrication, such as material fatigue and corrosion. The 18-8 Stainless Steel composition provides excellent resistance to rust and oxidation, extending service life in demanding conditions. The thread forming design eliminates the need for separate tapping operations, reducing assembly time and labor costs while creating strong, permanent threads. The wide truss head offers a larger bearing surface, distributing clamping force evenly to prevent sheet metal distortion and improve joint integrity. Ideal for HVAC, electronics enclosures, and automotive panels, this screw ensures reliable performance in industrial fastening applications where precision and durability are critical.

Specification Summary & Compliance

This screw features a thread diameter of 0.138" with approximately 18 threads per inch, adhering to standard inch measurements for consistent fit. The fully threaded shank and pointed tip facilitate easy insertion and secure fastening in pre-drilled holes (recommended drill bit: No. 32, 0.116" diameter). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for use in environmentally conscious manufacturing processes.
