About 12 Point Flange Nuts
12 Point Flange Nuts are specially engineered fasteners featuring a body divided into twelve equally spaced flats, allowing higher torque application compared to standard hex nuts. The 12-point design improves wrench engagement in confined spaces while ensuring precise load distribution across the joint. These nuts are commonly used with 12 point flange bolts or screws in high-performance and high-load assemblies.
Designed for strength and reliability, 12 Point Nuts are manufactured in high tensile grades and are available across a wide range of material categories and ASTM specifications. Dimensions are defined in both metric and imperial sizes with Unified National Coarse (UNC), Unified National Fine (UNF), Fixed Pitch (UN), and ISO metric thread profiles, making them suitable for demanding industrial, automotive, oil & gas, and engineering applications.
