S-96024A640 12-24 x 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 Stainless Steel construction, ensuring long-term reliability in harsh industrial environments.
• Effortless installation through thread cutting design that forms precise threads in brass, cast iron, and sheet metal without pre-tapped holes.
• Enhanced grip and load distribution thanks to the flanged hex head, reducing the risk of loosening under vibration and providing a larger bearing surface.
• Quick and secure fastening with external hex drive and coarse UNC threads, allowing for high torque application and rapid assembly in right-hand threading.
• Full-length threading for maximum holding power, ensuring consistent engagement along the entire 3/4" length in various material thicknesses.
• Optimized compatibility with No. 8 drill bit (0.199" diameter), simplifying hole preparation and reducing installation time.
• Compliance with global environmental standards including RoHS 3 and REACH, making them suitable for regulated industries and export requirements.

Professional Applications & Engineering Value

These 12-24 UNC thread cutting screws are engineered to address common challenges in metalworking and assembly, such as stripping threads and corrosion-induced failure. Made from 410 Stainless Steel, they resist rust and wear in demanding conditions, while the flanged hex head design eliminates the need for separate washers, speeding up installation in sheet metal, cast iron, and brass applications. The coarse UNC thread and thread cutting feature enable strong, self-tapping fastening without pre-tapped holes, reducing labor and material costs. Ideal for HVAC, automotive, and machinery assembly, these screws ensure reliable, vibration-resistant connections that maintain integrity over time, supported by full threading for uniform stress distribution.

Specification Summary & Compliance

This No. 12 tapping screw features a 12-24 UNC coarse thread with right-hand direction and full threading, adhering to standard dimensional tolerances for precise fit.
