S-90935A199 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel coating, extending service life in demanding industrial environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs.
• Optimized drill compatibility with No. 29 drill bit (0.136" diameter), ensuring precise hole preparation and secure fastening in materials up to 0.025" thickness.
• Enhanced drive stability from the Phillips No. 2 drive and pan head design, providing reliable torque transfer and reducing cam-out risks during installation.
• Full threading along the 1" length delivers maximum grip and uniform stress distribution, preventing loosening under vibration in sheet metal assemblies.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and meets global supply chain requirements for industrial projects.
• Right-hand thread and pointed tip facilitate quick alignment and smooth penetration, streamlining high-volume assembly operations.

Professional Applications & Engineering Value

This No. 8-15 thread forming tapping screw is engineered to address common challenges in sheet metal fastening, such as strip-out and vibration-induced failure. The black-oxide steel construction provides a durable, corrosion-resistant surface that withstands harsh conditions in HVAC, automotive, and construction applications. Its A/AB tapping screw type and fully threaded design ensure strong thread engagement without requiring pre-threaded holes, reducing assembly steps and improving production efficiency. The Phillips pan head offers a low-profile, secure fit that sits flush with surfaces, minimizing protrusion risks while maintaining high clamp force. Ideal for joining thin-gauge metals, this screw delivers reliable performance where precision and longevity are critical.

Specification Summary & Compliance

This screw features a No. 8-15 thread size with a 0.164" diameter and 15 threads per inch, adhering to standard inch measurements for consistent fit. The thread forming design complies with typical industrial tolerances, ensuring compatibility with No. 29 drill bits (0.136" diameter) for sheet metal up to 0.025" thick. Manufacturing follows recognized standards for right-hand threaded, fully threaded fasteners, and the product is verified as RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety regulations for global use.
