S-93406A198 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance in harsh environments due to premium 316 stainless steel material, ideal for outdoor or chemical-exposed applications.
• Superior holding power and reduced risk of pull-through with the wide truss head design, distributing load evenly across the sheet metal surface.
• Efficient, tool-compatible installation using a standard Phillips No. 2 drive, ensuring quick and secure fastening without stripping.
• Self-tapping capability eliminates pre-tapping needs, saving time and labor costs in sheet metal assembly up to 0.025" thickness.
• Full threading along the 5/8" length provides consistent grip and vibration resistance in dynamic industrial settings.
• Precision thread forming design creates strong, reliable threads in sheet metal without generating chips, maintaining joint integrity.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets global industrial standards for hazardous substance control.

Professional Applications & Engineering Value

Engineered for demanding sheet metal applications, this No. 8 tapping screw in 316 stainless steel addresses common industrial challenges like corrosion-induced failure and installation inefficiency. The thread forming method cold-forms threads into materials, eliminating chip debris and reducing the risk of galvanic corrosion in assemblies. With a Phillips truss head, it offers a low-profile, wide-bearing surface that prevents sinking into thin sheets, enhancing structural stability in HVAC, electronics enclosures, and automotive panels. Its self-tapping feature streamlines production by removing the need for separate tapping operations, while the fully threaded design ensures uniform stress distribution, making it a reliable choice for high-vibration environments where fastener loosening is a concern.

Specification Summary & Compliance

This screw features a thread diameter of 0.164" with approximately 15 threads per inch, adhering to standard inch measurements for precision fit. It is designed for use with a No. 29 drill bit (0.136" diameter) and complies with common industrial tolerances for thread-forming screws. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from restricted hazardous substances and suitable for global supply chains in industrial and electronic sectors.
