  • What is the difference between a hex head bolt and a hex head screw?

The difference between hex head bolts and hex head screws lies in their intended application and use.

Hexagon head bolts:
- Hex head bolts are designed for use with nuts to create a strong, secure connection between two or more components. It usually has a shank that is not threaded for part of its length, allowing it to be inserted into pre-drilled holes in the parts to be joined.
- Hex head bolts usually have heads that are larger and thicker than the threaded portion, and are designed to be tightened with a wrench or socket.
- Hex head bolts are typically used in applications that require a nut to hold the bolt in place, such as structural components, machinery, and automotive parts.

Hexagon head screws:
- Hex head screws, on the other hand, are designed to screw directly into a threaded hole, eliminating the need for a separate nut. It does not have an unthreaded shank and is fully threaded along its entire length.
- Hex head screws generally have smaller, more compact heads than hex head bolts and are designed to be tightened with a wrench or socket.
- Hex head screws are typically used in applications where components are fastened directly to threaded holes, such as machine components, electronic equipment, and wood products.

In summary, the main differences between hex head bolts and hex head screws are their intended use with or without nuts, and whether the bolts have an unthreaded shank.

  • What is a hex head nut?

A hex head nut, also known as a hex nut, is a fastener with a hexagonal shape with six sides. It is designed for use with mating bolts to secure two or more components together. The internal threads of the hex nut allow it to be threaded onto the external threads of the bolt, providing a secure and adjustable connection.

Hex head nuts are commonly used in a variety of applications including mechanical, construction, automotive and general manufacturing. They are available in a variety of materials, such as steel, stainless steel, brass and other non-ferrous metals, to suit different environments and load requirements.

The six-sided shape of the hex head nut allows for easy installation and removal using a wrench or socket, providing a safe and secure method of fastening components together.
