S-93406A079 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Enhanced load distribution from the wide truss head design (0.194" diameter), reducing material stress and preventing pull-through in thin sheet metal.
• Reliable thread forming technology creates strong, permanent threads in sheet metal without pre-tapping, ensuring vibration resistance and secure fastening.
• High precision threading with 32 TPI and fully threaded shank provides maximum grip and uniform clamping force along the entire 1/2" length.
• Efficient installation with No. 1 Phillips drive and pointed tip for quick alignment and reduced assembly time in metalworking projects.
• Compliance with environmental regulations, meeting RoHS 3 and REACH standards for safe, sustainable use in global supply chains.
• Optimized for sheet metal up to 0.025" thickness, with recommended No. 48 drill bit for precise, clean hole preparation.

Professional Applications & Engineering Value

These thread forming sheet metal screws address critical challenges in metal fabrication by eliminating the need for separate tapping operations. The 18-8 stainless steel composition provides excellent corrosion resistance, making them suitable for HVAC systems, electronic enclosures, and automotive assemblies where moisture or chemical exposure is a concern. The Phillips truss head design offers a low-profile, wide bearing surface that distributes clamping force effectively across thin sheet metal, preventing distortion and maintaining structural integrity. With 32 TPI precision threading and A/AB screw type compliance, these fasteners deliver consistent performance in high-vibration environments, reducing maintenance needs and improving product lifespan in industrial settings.

Specification Summary & Compliance

This No. 2 x 1/2" tapping screw features a right-hand thread direction, fully threaded round shank, and pointed tip for easy insertion. It adheres to standard inch measurements with precise thread forming specifications, including 0.086" thread diameter and 32 approximate threads per inch. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial and commercial applications worldwide.
