S-90315A467 Length 5/8" 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 creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling.
• Secure and flush finishing provided by the standard oval head, which sits neatly in countersunk holes for a smooth, professional appearance.
• Reliable driving performance with the No. 2 Phillips drive, ensuring high torque transfer and reduced risk of cam-out during installation.
• Full threading along the 5/8" length maximizes grip and holding power in sheet metal applications up to 0.025" thickness.
• Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe, sustainable use in global supply chains.
• Precision-engineered dimensions like the 0.312" head diameter and 15 threads per inch, guaranteeing consistent fit and performance in standardized assemblies.

Professional Applications & Engineering Value

This No. 8 x 5/8" Phillips Oval Head Tapping Screw is expertly crafted from 18-8 Stainless Steel to address common challenges in sheet metal fabrication, such as material fatigue and corrosion. The thread forming (Type A/AB) design displaces metal to form robust internal threads, eliminating the need for separate tapping operations and reducing assembly costs. Its fully threaded shank and pointed tip ensure quick starts and uniform load distribution, preventing loosening under vibration. Ideal for HVAC, automotive, and electronics enclosures, this screw provides a reliable, corrosion-resistant fastening solution that maintains integrity in demanding conditions, enhancing product lifespan and reducing maintenance.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a thread diameter of 0.164" and 15 threads per inch, ensuring precise fit in pre-drilled holes (recommended drill bit size No. 29, 0.136" diameter). The oval head features an 82° countersink angle for seamless installation. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing compliance with hazardous substance restrictions and supporting environmentally responsible manufacturing practices.
