S-90315A484 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant performance with 18-8 Stainless Steel construction, ensuring long-term reliability in harsh industrial environments.
• Efficient thread forming design eliminates the need for pre-drilling in sheet metal up to 0.025" thickness, reducing assembly time and labor costs.
• Secure Phillips drive (No. 2) provides reliable torque transfer and minimizes cam-out during installation for consistent fastening.
• Optimized oval head with 82° countersink sits flush with surfaces, offering a clean finish and reducing snagging risks.
• Full threading and pointed tip ensure quick, precise engagement and strong holding power in sheet metal applications.
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and meets international standards for industrial use.
• Standardized A/AB thread type and inch measurements ensure compatibility and easy integration into existing assembly systems.

Professional Applications & Engineering Value

These No. 8 x 1-3/4" stainless steel tapping screws are engineered to address common challenges in sheet metal assembly, where speed and durability are critical. The thread forming design creates strong, permanent threads in materials without pre-tapping, reducing the risk of strip-out and improving joint integrity. Made from 18-8 Stainless Steel, they resist corrosion from moisture, chemicals, and outdoor exposure, making them ideal for HVAC, automotive, and electronics enclosures. The oval head with Phillips drive and 82° countersink angle ensures a low-profile, secure fit that withstands vibration, while the fully threaded shank distributes load evenly. This combination enhances assembly efficiency and extends service life in demanding industrial applications.
