S-95639A307 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Superior thread-forming performance creates strong, reliable threads in sheet metal without pre-tapping, reducing assembly time and tooling costs.
• Optimized for sheet metal applications with a maximum drilling thickness of 0.025", ensuring secure fastening in thin materials.
• Clean, finished appearance with a standard oval head that sits flush against surfaces, providing a professional look and reducing snagging.
• Efficient installation using a No. 1 Phillips drive, offering good torque transfer and reducing the risk of cam-out during driving.
• Full threading for maximum grip along the entire 5/8" length, delivering consistent holding power across the entire fastened joint.
• Environmentally responsible manufacturing with full compliance to RoHS 3 and REACH regulations, ensuring safety and sustainability.

Professional Applications & Engineering Value

These 316 stainless steel Phillips oval head tapping screws are engineered to address common challenges in sheet metal fabrication and assembly. The thread forming (Type A/AB) design displaces material to create strong, wear-resistant internal threads, eliminating the need for separate tapping operations and reducing labor costs. This is particularly valuable in high-volume production environments where speed and reliability are critical. The corrosion-resistant 316 stainless steel material ensures long-term durability in demanding conditions, including those exposed to moisture, chemicals, or salt spray, making these screws ideal for industrial equipment, enclosures, and HVAC systems. The combination of a pointed tip and precise No. 4-24 thread ensures easy starting and consistent performance, minimizing the risk of cross-threading and improving overall assembly quality.

Specification Summary & Compliance

This screw conforms to standard inch dimensions: Size No. 4, thread diameter of 0.112", and 24 threads per inch (TPI) with a right-hand thread direction. It is fully threaded and features a Class 2A thread fit for general applications. The manufacturing and material composition adhere to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring they are free from hazardous substances and suitable for global industrial use.
