S-90066A312 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced driving efficiency through external hex drive design allowing high torque application and secure fastening
• Optimal material displacement with thread forming (A/AB) design that creates strong, permanent threads in sheet metal without chip removal
• Integrated sealing and load distribution from steel/rubber flat washer that prevents loosening and protects material surfaces
• Full-length thread engagement with pointed tip for maximum holding power across the entire 5/8" length in sheet metal applications
• Precision compatibility with standard 5.5mm drill bits (0.2165") for simplified installation in materials up to 0.025" thickness
• Reliable performance consistency with No. 14-10 thread specification ensuring predictable fastening behavior in production environments

Professional Applications & Engineering Value

These zinc-plated steel hex washer tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming design eliminates the risk of metal chip accumulation in sensitive equipment while creating stronger, more reliable threads than cutting alternatives. The combination of steel/rubber flat washer provides both vibration resistance and environmental sealing, crucial for automotive, HVAC, and electronic enclosure applications. With fully threaded construction and pointed tip, these fasteners ensure maximum thread engagement and easier starting in pre-drilled holes. The external hex drive accommodates high-torque installation tools, making them ideal for production line environments where speed and reliability are paramount.

Specification Summary & Compliance

This No. 14-10 tapping screw features a 0.242" thread diameter with 10 threads per inch in right-hand thread configuration. Manufactured to A/AB thread forming standards with Class 2A thread tolerances for consistent performance. The fastener is RoHS 3 (2015/863/EU) compliant, meeting environmental regulations for industrial use. Designed for use with 5.5mm (0.2165") drill bits in materials up to 0.025" maximum drilling thickness, ensuring proper fit and optimal thread formation in sheet metal applications.
