"Product Technical Specifications
IMScrews 3/8-16 Flange Nuts are engineered from reliable 18-8 (304) stainless steel, offering consistent resistance against rust and environmental elements. These fasteners feature a serrated flange base that provides a strong grip to help maintain a stable connection in environments prone to movement or vibration. With a wide 18.6mm bearing surface, these nuts effectively distribute load across the material, preventing surface damage and ensuring structural integrity.

Design and Application Guidance
Designed for versatility, these serrated lock nuts are a dependable choice for automotive repairs, industrial machinery, and outdoor construction projects. The integrated flange design eliminates the need for separate washers, streamlining the assembly process. Please note that while 304 stainless steel is highly reliable, these fasteners may exhibit a slight magnetic pull due to the cold-forging process used during manufacturing, which is a common physical characteristic of the material.
