S-90086A624 10-24 x 2" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior material durability with zinc-plated steel construction providing excellent corrosion resistance for long-lasting performance in harsh industrial environments.
• Efficient thread cutting capability with Type F tapping design creates precise threads in aluminum, brass, cast iron, and sheet metal without pre-tapping requirements.
• Optimized drive performance through Phillips No. 2 drive style ensures secure torque transmission and reduces cam-out during installation.
• Full 2-inch threading delivers maximum grip length and superior holding power across the entire fastener length.
• Standard 82° flat head profile enables flush mounting and clean finishes in countersunk applications.
• Reliable coarse UNC threading (10-24) provides quick installation and superior resistance to vibration loosening.
• Industry compliance assurance with ASME B18.6.3 standards and RoHS 3 compliance guarantees consistent quality and environmental responsibility.

Professional Applications & Engineering Value

These 10-24 UNC zinc-plated steel tapping screws are engineered specifically for demanding metal fabrication and assembly applications. The thread cutting design (Type F) eliminates the need for separate tapping operations in materials like aluminum, brass, cast iron, and sheet metal, significantly reducing installation time and labor costs. The zinc-plated steel construction provides essential corrosion protection in industrial environments, while the Phillips No. 2 drive ensures reliable torque transfer without specialized tools. The coarse UNC threading maintains secure fastening in vibration-prone applications, and the flat head profile with 82° countersink angle delivers clean, flush finishes in visible applications. These industrial-grade fasteners solve critical assembly challenges by combining material compatibility with installation efficiency.
