The bottom of the Inch hexagon thick nuts with washer faced is flattened and widened (" washer face "), and its function is similar to that of an internal washer. They are thicker than standard nuts, can withstand heavy loads, and the washer surface can evenly distribute the pressure.
The surface of Inch hexagon thick nuts with washer faced made of stainless steel (304/316) is more resistant to rust than that of carbon steel. For high-temperature environments (exhaust systems), alloy steel nuts (ASTM A194) can withstand expansion without deformation. Avoid using galvanized coatings in acidic environments as they will peel off. Apply anti-seizing agent to the threads to prevent seizing, especially under high-temperature conditions.
The Inch hexagon thick nuts with washer faced is used in high-vibration devices, such as engines, agricultural equipment or construction equipment, which can prevent loosening due to vibration. They are also very suitable for rusty or uneven joints where standard nuts may be tilted. Farmers use them when ploughing fields, mechanics use them on truck suspensions, and they are also used on assembly lines in factories.
Inch hexagon thick nuts with washer faced can solve two problems simultaneously: grip and protection. The hexagonal shape makes it convenient to use the wrench from any Angle, while the flat shape prevents the surface of the nut from being damaged. The size range is available from ½ inches to 2 inches. These nuts are a little more expensive than ordinary nuts, but they can save the cost of later maintenance.
The Inch hexagon thick nuts with washer faced adopts a stable bottom, which can disperse the force and prevent scratches. However, standard thick nuts will be embedded in the surface under load, damaging the soft material. Their installation speed is also faster, and there is no need to look around for matching gaskets. In high-vibration applications, washer face nuts are more effective in preventing loosening than ordinary nuts. Ordinary thick nuts can be used in non-critical working scenarios.
