S-93406A158 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term outdoor applications.
• Superior holding power in sheet metal due to the thread forming design, creating strong, reliable threads without pre-tapping.
• Wide truss head design provides a larger bearing surface for enhanced load distribution and reduced risk of pull-through.
• High-strength fastening with a fully threaded No. 6 shank and 18 TPI, ensuring maximum engagement and vibration resistance.
• Effortless installation using a standard Phillips No. 2 drive, compatible with common tools for efficient assembly.
• Pre-engineered compatibility with a No. 32 drill bit (0.116" diameter), simplifying hole preparation for up to 0.025" thick materials.
• Environmentally responsible manufacturing, fully compliant with RoHS 3 and REACH regulations for safe, sustainable use.

Professional Applications & Engineering Value

This No. 6 x 1-1/2" truss head tapping screw is engineered to solve critical challenges in sheet metal assembly. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for HVAC systems, electronic enclosures, and automotive panels exposed to moisture. Its thread forming technology (Type A/AB) displaces material to form precise internal threads, eliminating the need for separate tapping operations and reducing assembly time and cost. The wide truss head offers a low-profile yet large clamping area, preventing sheet distortion and ensuring a secure fit in thin-gauge metals. The Phillips drive allows for high-torque installation without cam-out, enhancing productivity in high-volume manufacturing lines.

Specification Summary & Compliance

This screw features a No. 6 thread diameter (0.138") with 18 TPI and a 1-1/2" length, fully threaded for consistent performance. It is designed for use with a No. 32 drill bit (0.116" diameter) and complies with industry standards for thread forming tapping screws. The product is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it is free from hazardous substances and safe for industrial applications.
