S-96024A630 12-24 x 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Self-tapping efficiency – Thread cutting design eliminates pre-tapping needs, reducing installation time and labor costs in brass, cast iron, and sheet metal assemblies.
• Enhanced corrosion resistance – Made from 410 stainless steel for reliable performance in demanding industrial environments and extended service life.
• Secure, high-torque fastening – External hex drive with flanged head distributes clamping force evenly and prevents pull-through in thin materials.
• Optimized for coarse UNC threading – 12-24 UNC coarse thread ensures rapid installation and strong holding power in a variety of base materials.
• Full-thread engagement – Fully threaded shank maximizes grip length and load distribution across the entire fastener.
• Precision fit and reduced tool wear – Designed for use with a No. 8 drill bit (0.199"), ensuring clean threads and minimizing installation errors.
• Regulatory compliance assurance – Meets RoHS 3 and REACH standards, supporting your supply chain’s environmental and safety requirements.

Professional Applications & Engineering Value

This 12-24 UNC thread cutting screw is engineered to address common challenges in metalworking and assembly, such as stripping, corrosion, and time-consuming tapping operations. The Type F thread cutting design allows the screw to form its own mating threads in brass, cast iron, and sheet metal, eliminating the need for separate tapping and reducing assembly steps. Constructed from 410 stainless steel, it provides excellent resistance to oxidation and mild chemicals, making it suitable for outdoor equipment, HVAC systems, and machinery exposed to humidity. The flanged hex head offers a larger bearing surface, which helps prevent the screw from sinking into softer materials and allows for higher torque application with standard hex tools. This combination of self-tapping capability, durable material, and user-friendly design streamlines production, lowers total cost of ownership, and enhances joint integrity in high-vibration environments.
