A563 American Standard Heavy Hex Nuts Manufacturer In China

Ningbo Teng Qi Fasteners Co., Ltd is a leading American Standard A563 heavy hex nuts manufacturer in China. The A563 heavy hex nut is a specific type of nut that conforms to the ASTM A563 standard. ASTM A563 is a specification that covers various grades of carbon and alloy steel nuts used in construction and industrial applications. The heavy hex nut is designed with a larger width across the flats compared to a standard hex nut, which provides a larger bearing surface and increased load-carrying capability.

These nuts are typically used in structural and heavy-duty applications, such as in the construction of buildings, bridges, and other steel structures. They are often used in conjunction with ASTM A325 or A490 structural bolts for joining steel components.

The different grades of A563 heavy hex nuts (A563 Grade A, A563 Grade DH, and others) correspond to various strength levels and material compositions, each suitable for different types of applications and environmental conditions. It’s important to choose the appropriate grade based on the specific requirements of your project.

Specification of A563 American Standard Heavy Hex Nuts:

Here is the specification related to A563 heavy hex nuts:

1. Diameter: The diameter of an A563 nut refers to the size of the nut’s threaded hole. It is typically specified using a measurement like 1/2″, 5/8″, or 3/4″, indicating the inner diameter.

2. Grade: The grade of an A563 heavy hex nut signifies its strength and material properties. A563 nut come in different grades, such as A563 Grade A, A563 Grade B, or A563 Grade DH, each with specific requirements for strength and performance.

3. Material: The material of an A563 heavy hex nut is what it’s made from. These nuts are commonly made from carbon steel or alloy steel, depending on the grade, to meet specific strength and performance requirements.

4. Surface Treatment: Surface treatment refers to any coating or finish applied to the outer surface of the A563 heavy hex nut.
