• Enhanced load distribution and stability provided by the integrated flange, reducing the risk of loosening under vibration.
• Precise and reliable fastening with UNF fine threads and fully threaded shank, ensuring consistent grip and high pull-out strength.
• Robust 2-inch length ideal for thicker material sections, offering versatile application across various industrial assemblies.
• Compliance with industry standards including ASME B18.6.3 and RoHS 3, guaranteeing quality, safety, and environmental responsibility.

Professional Applications & Engineering Value

These 10-32 zinc-plated steel flanged hex tapping screws are engineered to address common challenges in metalworking and assembly, such as the need for reliable fastening in materials that are difficult to tap. The thread cutting (Type F) design allows for direct installation into aluminum, brass, cast iron, and sheet metal, eliminating the time and cost associated with pre-drilling and tapping operations. The external hex/slotted drive ensures high torque application without stripping, while the flanged head distributes clamping force evenly, preventing surface damage and maintaining joint integrity under dynamic loads. This makes them ideal for heavy-duty industrial applications in automotive, machinery, and construction, where vibration resistance and durability are critical.

Specification Summary & Compliance

This product features a 10-32 UNF fine thread with a fully threaded shank and blunt tip, designed for precise thread cutting in accordance with ASME B18.6.3 standards. The screws are manufactured from zinc-plated steel and comply with RoHS 3 (2015/863/EU) regulations, ensuring they are free from hazardous substances. Key dimensions include a 2-inch length, 0.313-inch head width, and 0.414-inch flange diameter, providing consistent performance and reliability in specified applications.
