"Product Technical Specifications
IMScrews 1/2-13 Flange Nuts are engineered from reliable 18-8 (304) stainless steel, offering consistent resistance against rust and environmental corrosion. These heavy-duty fasteners feature a serrated flange base that provides a strong grip to help maintain a stable connection in environments prone to high vibration. The wide flange base effectively distributes load across the material, preventing surface damage and ensuring structural integrity in professional assemblies.

Design and Application Guidance
Designed for structural durability, these serrated hex nuts are a dependable choice for automotive chassis, suspension components, and outdoor construction projects. The integrated flange design eliminates the need for separate washers, streamlining the assembly process in tight or complex spaces. Please note that these 304 stainless steel fasteners exhibit a noticeable magnetic pull due to the intense cold-forming process used for heavy 1/2-inch hardware, which is a common physical characteristic of the material.
