S-90065A053 Length 5/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and long-term reliability.
• Efficient thread forming design (AB Type) creates strong, permanent threads in sheet metal without chips, reducing assembly time and tool wear.
• Precise 82° countersink angle ensures a flush, professional finish in sheet metal applications, minimizing protrusion and snagging risks.
• High thread density (42 TPI) provides excellent grip and vibration resistance in thin materials, enhancing joint integrity.
• Durable Phillips No. 0 drive offers reliable torque transmission and reduces cam-out during installation, improving work efficiency.
• Fully threaded shank maximizes holding power across the entire length, ensuring secure fastening in varied material thicknesses.
• Compliance with RoHS 3 and REACH guarantees environmental safety and regulatory adherence for global supply chain requirements.

Professional Applications & Engineering Value

These thread forming screws are engineered to address common challenges in sheet metal assembly, such as material fatigue and corrosion. The 18-8 stainless steel composition delivers exceptional strength and corrosion resistance, making them suitable for demanding environments like HVAC systems, electronic enclosures, and automotive panels. The AB type tapping method forms threads without cutting, which eliminates swarf and reduces the risk of loose particles in sensitive equipment. With a flat head design and 82° countersink, they sit flush to maintain aerodynamic surfaces and prevent interference. The Phillips drive ensures easy installation with standard tools, streamlining production lines while providing reliable performance in high-vibration applications.

Specification Summary & Compliance

This product features a thread diameter of 0.073" with approximately 42 threads per inch, adhering to standard tapping screw dimensions for precise fit. The flat head profile and fully threaded design comply with industry practices for sheet metal fastening. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance and safety for industrial use.
