hexagonal bolt, commonly known as a hex bolt or hexagon head bolt, is a type of fastener that features a six-sided head. It is designed to be tightened or loosened using a wrench or socket with a matching hexagonal shape.

Here are some key features and characteristics of hexagonal bolts:

1. Head: The head of a hexagonal bolt is hexagonal in shape, with six flat sides and angles of 120 degrees. This design provides multiple points of contact for a wrench or socket, allowing for efficient torque application during tightening or loosening.

2. Threaded Shank: The shank of a hexagonal bolt is threaded along its entire length, allowing it to engage with a corresponding threaded hole or nut. The threads can be coarse or fine, depending on the specific application requirements.

3. Materials and Finishes: Hexagonal bolts are available in various materials, including steel, stainless steel, brass, and other alloys. They can also be coated or plated with different finishes to enhance corrosion resistance or provide an aesthetic appearance.

4. Size and Length: Hexagonal bolts come in a wide range of sizes and lengths to suit different applications. They are typically measured based on their diameter (thread size) and length, following standard metric or imperial measurements.
