S-90390A143 10-24 x 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with T20 Torx drive design, reducing cam-out and tool slippage during installation
• Enhanced corrosion resistance through zinc-plated steel construction, extending service life in industrial environments
• Efficient thread cutting action with Type F tapping design, eliminating the need for pre-tapped holes in aluminum, brass, and cast iron
• Secure flush mounting with standard 82° flat head profile, providing smooth surface finishes in sheet metal applications
• Quick installation through UNC coarse threading and fully threaded design, reducing assembly time in high-volume production
• Reliable material compatibility with pre-specified No. 17 drill bit size, ensuring proper hole preparation for optimal thread engagement
• Environmental compliance with RoHS 3 standards, meeting international regulatory requirements for industrial components

Professional Applications & Engineering Value

These 10-24 thread cutting screws deliver exceptional value in metal fabrication and assembly operations. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength for demanding applications. Engineered with UNC coarse threads and Type F tapping geometry, these fasteners effectively cut their own mating threads in aluminum, brass, cast iron, and sheet metal without requiring pre-tapped holes. The T20 Torx drive system ensures maximum torque transfer, preventing fastener damage during high-torque installation. This combination of features addresses common industrial challenges including stripped drive heads, cross-threading issues, and premature corrosion failure in metal-to-metal fastening applications.

Specification Summary & Compliance

These tapping screws feature precise UNC coarse threading with standard Class 2A tolerance for consistent engagement. The 3/4" length and 0.19" thread diameter provide optimal fastening depth for various material thicknesses. Manufactured to industry standards for thread cutting screws, these fasteners are fully compliant with RoHS 3 (2015/863/EU) environmental regulations, ensuring they meet current restrictions on hazardous substances for industrial and commercial applications.
