S-93406A152 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh or humid industrial environments where rust prevention is critical.
• Superior grip and load distribution from the wide truss head design, minimizing the risk of pull-through in thin sheet metal applications.
• Efficient, secure thread-forming installation that creates strong, permanent threads in pre-drilled holes without the need for tapping, reducing assembly time and tooling.
• Optimized for 0.025" maximum drilling thickness when used with a No. 32 drill bit (0.116" diameter), ensuring precise fit and maximum holding power in sheet metal.
• Reliable drive engagement with a Phillips No. 2 drive, providing common tool compatibility and reducing cam-out during installation for consistent torque application.
• Full threading for maximum engagement along the entire 5/8" length, offering versatile fastening points and enhanced resistance to vibration loosening.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring they are safe for use in regulated industries and global supply chains.

Professional Applications & Engineering Value

This 316 stainless steel Phillips truss head tapping screw is engineered to solve critical challenges in sheet metal fabrication and assembly. The thread forming (Type A/AB) design displaces material to create strong, clean internal threads without generating chips, which is vital for preventing electrical shorts and contamination in sensitive assemblies. The combination of a wide truss head and fully threaded shank provides exceptional clamp force and resists vibration-induced failure, a common issue in automotive, HVAC, and electronic enclosure applications. Manufactured from 316 stainless steel, it delivers superior performance in corrosive environments, such as marine or chemical processing, where fastener integrity is non-negotiable. This makes it an indispensable industrial screw for engineers prioritizing long-term reliability and reduced maintenance.

Specification Summary & Compliance

This screw conforms to standard inch measurements with a No. 6 screw size, 0.138" thread diameter, and 18 threads per inch. The thread forming tapping method and A/AB screw type are designed for creating mating threads in ductile materials. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted hazardous substances and suitable for use in demanding industrial and commercial applications.
