S-90197A242 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient self-tapping installation through thread-forming design that eliminates the need for pre-tapped holes
• Enhanced torque transfer with external hex drive style for secure fastening and reduced tool slippage
• Integrated flange design provides wider bearing surface for improved load distribution and vibration resistance
• Optimized for sheet metal applications with needle point tip that penetrates materials up to 0.05" thickness efficiently
• Full threading coverage ensures maximum grip strength and pull-out resistance along the entire fastener length
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 10-12 thread zinc-plated steel flanged tapping screws deliver exceptional performance in sheet metal fastening applications where reliability and corrosion resistance are critical. The thread-forming tapping method creates precise mating threads in base materials, eliminating the need for separate tapping operations and reducing assembly time. The combination of external hex drive and flange design provides superior clamping force distribution while preventing head pull-through in thin gauge materials. Engineered specifically for sheet metal applications requiring penetration up to 0.05" thickness, these self-tapping screws with their needle point tip ensure quick starts and reduced driving torque, making them ideal for high-volume production environments where efficiency and consistent performance are paramount.

Specification Summary & Compliance

This No. 10 tapping screw features a 1/2" length with 0.19" thread diameter and 12 threads per inch configuration. The fastener includes a 1/4" hex head width with 0.141" head height and 0.348" flange diameter for optimal load distribution. Manufactured as a fully threaded, right-hand thread direction screw with round shank cross-section, it's designed for use with No. 21 drill bit (0.159" diameter). The product maintains compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety standards are met for industrial applications.
