S-93406A247 Length 1" 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 in sheet metal assemblies.
• Enhanced load distribution from the wide truss head design, reducing the risk of material pull-through and providing a larger bearing surface.
• Efficient thread forming (Type A/AB) creates strong, permanent threads in sheet metal without pre-tapping, saving installation time and labor.
• High driving torque capability with the No. 2 Phillips drive, minimizing cam-out and ensuring secure fastening in demanding applications.
• Full threading along the 1" length offers maximum grip and uniform clamping force across the entire fastened material thickness.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets global industrial standards for hazardous substance restrictions.
• Optimized for 0.025" maximum sheet thickness with a pointed tip for easy starting and precise alignment in metal fabrication.

Professional Applications & Engineering Value

These No. 10-12 x 1" Phillips Truss Head Tapping Screws are engineered to address common challenges in sheet metal fabrication, such as material fatigue and corrosion. The 18-8 Stainless Steel provides excellent resistance to rust and oxidation, making them suitable for outdoor or humid environments. The thread forming design (Type A/AB) eliminates the need for separate tapping operations, reducing assembly time and preventing thread stripping in thin-gauge metals. The wide truss head profile distributes clamping force evenly, minimizing stress concentrations and preventing sheet deformation. This combination of corrosion-resistant material and high-strength threading ensures reliable performance in HVAC systems, electronic enclosures, and automotive panels, where vibration resistance and durability are critical.

Specification Summary & Compliance

This screw features a No. 10-12 thread with a diameter of 0.19" and approximately 12 threads per inch, manufactured to standard inch measurements. It is fully threaded with a right-hand direction and pointed tip for efficient penetration. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from restricted hazardous substances. Designed for use with a No. 21 drill bit (0.159" diameter), it meets typical industrial requirements for thread forming tapping screws in sheet metal applications.
