S-93945A013 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-lasting performance in demanding industrial environments.
• Efficient thread forming creates strong, secure threads in sheet metal without pre-tapping, reducing assembly time and labor costs.
• Optimal flush mounting with a standard flat head and 82° countersink angle for a smooth, professional finish in sheet metal applications.
• Enhanced drive stability provided by the No. 2 square drive, minimizing cam-out and ensuring reliable torque transmission.
• Full threading along the entire 5/8" length delivers maximum grip and holding power in materials up to 0.025" thickness.
• Precision compatibility with a No. 29 drill bit (0.136" diameter), ensuring accurate hole preparation and secure fastening.
• Environmental and safety compliance with RoHS 3 and REACH regulations, making them suitable for global supply chains and sensitive applications.

Professional Applications & Engineering Value

These No. 8-15 thread forming screws are engineered to address common challenges in sheet metal fabrication, such as material fatigue and strip-out. The 18-8 stainless steel provides excellent resistance to rust and oxidation, crucial for outdoor or high-moisture environments. The thread forming design displaces material rather than cutting it, resulting in stronger thread engagement and reduced risk of loosening under vibration. With a 0.164" thread diameter and 15 threads per inch, they offer a fine balance of grip strength and installation ease. The flat head with an 82° countersink ensures a flush fit, preventing snagging and improving aesthetics in visible assemblies. Ideal for HVAC, electronics enclosures, and automotive panels, these screws streamline production while maintaining high durability and reliability.

Specification Summary & Compliance

This product adheres to standard inch measurements with a No. 8 screw size, 5/8" length, and fully threaded shank. The thread forming (Type A/AB) tapping method and right-hand thread direction follow industry conventions for sheet metal fastening. Precision is maintained with a Class 2A thread fit (typical for inch-series screws), ensuring consistent performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), these screws meet stringent environmental and safety standards, making them suitable for regulated industries and international markets.
