S-90197A648 Length 1" 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 thread-forming capability with pointed needle tip design creates permanent, vibration-resistant threads in sheet metal
• Integrated flange eliminates need for separate washers, reducing assembly time and component count while providing superior load distribution
• External hex/slotted drive system offers versatile installation options for both manual and power tool applications
• Optimized for 0.05" maximum drilling thickness in sheet metal applications, ensuring reliable performance in thin material assemblies
• Full 1" threading provides maximum engagement and holding power throughout the entire fastener length
• Precision No. 10-12 thread profile delivers consistent performance and reliable fastening in standardized applications

Professional Applications & Engineering Value

These No. 10-12 x 1" zinc-plated steel flanged hex tapping screws are engineered specifically for sheet metal applications where vibration resistance and corrosion protection are critical. The thread forming technology eliminates the need for pre-tapped holes, creating stronger, more durable threads that won't strip under stress. The flanged hex design combines the installation convenience of an external hex drive with the load distribution benefits of an integrated washer, making them ideal for HVAC systems, electrical enclosures, and metal fabrication projects. The zinc-plated steel construction provides excellent corrosion resistance while maintaining the high tensile strength required for industrial fastening applications, ensuring long-term reliability in challenging environments.

Specification Summary & Compliance

These tapping screws feature precision No. 10-12 thread with 0.19" thread diameter and 12 threads per inch, designed for use with No. 21 drill bit (0.159" diameter) in sheet metal up to 0.05" thickness. The fully threaded design with right-hand threading and pointed tip ensures optimal performance in thread forming applications. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, these fasteners meet the highest standards for industrial use while ensuring environmental responsibility.
