Hex Nuts

What is hex nuts?

Fastener nuts are a type of hardware used to secure objects in place. They are small, typically hexagonal-shaped pieces made of metal or other materials, and they have internal threads that allow them to be screwed onto a bolt or screw. When the nut is tightened onto the bolt or screw, it creates a secure connection between two objects.

Hex nuts are one of the most commonly used types of fasteners in industrial and construction applications. They are typically made of metal and have six sides or faces, which provide a secure grip for tightening and loosening with a wrench or pliers. Here are some common specifications for hex nuts:

1. Size: Hex nuts come in a range of sizes, typically measured by the distance across opposite faces, known as the "across flats" measurement. Common sizes include 1/4", 5/16", 3/8", 1/2", 5/8", 3/4", 7/8", and 1".

2. Thread: Hex nuts have internal threads that match the external threads of a bolt or screw. The thread size is usually specified in terms of the diameter and thread pitch, such as "1/4-20" or "3/8-16". The first number indicates the diameter of the bolt or screw, and the second number indicates the number of threads per inch.

3. Material: Hex nuts can be made from a variety of materials, including steel, stainless steel, brass, and nylon. The material chosen will depend on factors such as the application, the environment, and the desired level of corrosion resistance.

4. Finish: Hex nuts can be finished in a variety of ways to improve their appearance or provide additional protection against corrosion. Common finishes include plain (uncoated), zinc-plated, black oxide, and hot-dip galvanized.

5. Strength: Hex nuts are available in various grades or classes that indicate their strength and hardness. The most common grades are 2, 5, and 8, which correspond to a minimum tensile strength of 50,000, 120,000, and 150,000 psi, respectively. High-strength nuts are often marked with a symbol such as a radial line or the letter "H" to indicate their grade.
