Product Description

Custom Metric Serrated Hex Flange Nuts Zinc Plated Yellow Zinc Black Finish Flange Lock Nuts for Industrial Machinery and Automotive Fastening

Our custom metric serrated hex flange nuts are designed for stable fastening in industrial machinery, automotive parts, equipment assembly, repair work, and general hardware applications. The product combines a standard hex nut body with an integrated flange base, helping improve contact area and fastening stability during installation.

The serrated flange design helps increase grip on the mating surface and helps reduce loosening in applications where vibration may occur. Compared with regular hex nuts, flange nuts can simplify assembly because the flange works as a built-in washer, reducing the need for separate flat washers in many fastening situations.

This product is available with different surface appearances shown in the image, including silver zinc plated, yellow zinc plated, and black finish, giving buyers more options for different project requirements, product matching, and market demand.
