S-90315A489 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability.
• Effortless installation using a standard Phillips No. 2 drive, reducing tool slippage and assembly time.
• Strong, permanent threads formed directly in sheet metal, eliminating the need for pre-tapped holes and providing excellent pull-out resistance.
• Clean, finished appearance with a standard oval head that sits flush in a countersunk hole for a professional look.
• Full-length threading ensures maximum grip and holding power along the entire 2-1/2" length in sheet metal applications.
• Regulatory compliance with RoHS 3 and REACH, ensuring safety and environmental standards are met for industrial use.
• Optimized for 0.025" maximum sheet thickness with a pointed tip and specific drill bit size (No. 29) for precise, secure fastening.

Professional Applications & Engineering Value

These No. 8 oval head tapping screws are precision-engineered from 18-8 Stainless Steel to solve common industrial challenges like corrosion and assembly efficiency. The thread forming design (Type A/AB) creates strong, load-bearing threads in sheet metal without chips, preventing loosening from vibration. The Phillips drive and fully threaded shank ensure quick installation and superior holding strength, making them a reliable choice for HVAC, electronic enclosures, and automotive panels where durability and a clean finish are critical.

Specification Summary & Compliance

This screw features a No. 8 size with a 0.164" thread diameter and approximately 15 threads per inch, conforming to standard inch measurements. The oval head is designed for an 82° countersink angle. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), meeting stringent industrial safety and environmental regulations.
