ASME B18.16.4 Hexagon Flange Nuts

ASME B18.16.4 Hexagon Flange Nuts

Overview
The ASME B18.16.4 Hexagon Flange Nuts are high-strength, precision-manufactured fasteners designed to provide secure clamping and superior load distribution in mechanical assemblies. Conforming to the ASME B18.16.4 standard, these flange nuts feature a built-in washer-like flange at the base, which helps spread the load over a larger surface area, reducing surface pressure and enhancing joint integrity. The ASME B18.16.4 Hexagon Flange Nuts are widely used in automotive, construction, heavy machinery, and industrial manufacturing applications where vibration resistance and uniform pressure are essential.

Key Features of ASME B18.16.4 Hexagon Flange Nuts

1. Integrated Flange Base
   The defining feature of the ASME B18.16.4 Hexagon Flange Nuts is the wide, serrated or smooth flange that functions like a built-in washer. This helps distribute clamping force evenly and reduces the chance of damage to connected surfaces.

2. Hexagonal Shape for Tool Compatibility
   The six-sided design allows for easy tightening with standard wrenches and sockets, making installation of ASME B18.16.4 Hexagon Flange Nuts fast and efficient, even in high-torque conditions.

3. Standardized Dimensions
   Manufactured in accordance with ASME B18.16.4, these nuts meet strict dimensional tolerances, thread profiles, and mechanical property requirements—ensuring global compatibility and consistent performance.

4. Anti-Loosening Functionality
   The optional serrated flange design of ASME B18.16.4 Hexagon Flange Nuts provides a locking feature that resists loosening under vibration, making them ideal for dynamic environments such as engines or rotating equipment.

5. Material and Finish Options
   ASME B18.16.4 Hexagon Flange Nuts are available in carbon steel, stainless steel, alloy steel, and brass. Surface finishes include zinc plating, hot-dip galvanizing, black oxide, or plain, depending on corrosion resistance requirements.
