Types of Hex Bolts Commonly Used in Construction and Manufacturing
Hex bolts, also known as hexagonal head bolts, are a type of fastener with a six-sided head that is widely used in construction, machinery, and other industries. They are known for their strength, versatility, and ease of installation. Here are some of the most common types of hex bolts:
1. Hex Bolt with Nut:
This type of bolt consists of a hex bolt and a nut, and it is used to connect two or more pieces that can be disassembled and reassembled easily.
Hex bolts with nuts are available in a wide range of sizes, strength grades, and nut types.
Applications: These bolts are commonly used in applications that require frequent disassembly and reassembly, such as machine covers, doors, and valves.

Applications: These bolts are commonly used in applications that require frequent disassembly and reassembly, such as machine covers, doors, and valves.
2. Fully Threaded Hex Bolt:
This type of bolt has threads that extend the entire length of the shank, making it suitable for applications where the bolt needs to pass through a hole in both pieces being connected.
Fully threaded hex bolts are available in a variety of sizes, strength grades, and materials.
Applications: These bolts are commonly used in construction, machinery, and equipment assembly.
Fully threaded hex bolts are available in a variety of sizes, strength grades, and materials.
Applications: These bolts are commonly used in construction, machinery, and equipment assembly.
3. Partially Threaded Hex Bolt:
This type of bolt has threads that only extend partway up the shank, leaving an unthreaded portion that acts as a spacer.
Partially threaded hex bolts are available in a variety of sizes, strength grades, and materials.
Applications: These bolts are commonly used in applications where the bolt needs to be flush with the surface of one of the pieces being connected.
4. Hex Lag Bolt:
This type of bolt has a long shank and a tapered head, and it is used to anchor objects into wood, concrete, or other masonry materials.
Hex lag bolts are available in a variety of sizes, strength grades, and materials.
Applications: These bolts are commonly used to install door frames, window frames, and other fixtures.
Applications: These bolts are commonly used to install door frames, window frames, and other fixtures.
5. Hex Carriage Bolt:
This type of bolt has a round head with a slightly raised top, and it is used to connect two or more pieces that are not flush with each other.
Hex carriage bolts are available in a variety of sizes, strength grades, and materials.
Applications: These bolts are commonly used in agricultural and construction applications.
Materials Used for Hex Bolts:
Hex bolts are made from a variety of materials, each with its own advantages and disadvantages. The most common materials include:
Steel: The most common material for hex bolts is steel, which is strong, durable, and relatively inexpensive. Steel hex bolts are available in a variety of strength grades, from low-strength to high-strength.
Stainless Steel: Stainless steel hex bolts are more resistant to corrosion than steel hex bolts, making them a good choice for outdoor applications or applications where the bolts will be exposed to moisture.
Brass: Brass hex bolts are more aesthetically pleasing than steel or stainless steel hex bolts, and they are also more resistant to corrosion. However, brass is not as strong as steel or stainless steel.
Selecting the Right Hex Bolt:
When selecting a hex bolt, it is important to consider the following factors:
Size: The size of the bolt will be determined by the size of the hole in the pieces being connected.
Strength Grade: The strength grade of the bolt will be determined by the amount of force that the bolt will need to withstand.
Material: The material of the bolt will be determined by the environment in which the bolt will be used.
Type: The type of bolt will be determined by the application.
Additional Considerations:
In addition to the factors listed above, there are a few other things to keep in mind when selecting hex bolts:
Finish: Hex bolts are available in a variety of finishes, such as plain, zinc-plated, and black oxide. The finish will affect the appearance of the bolt and its resistance to corrosion.
Thread Type: Hex bolts are available with standard or coarse threads. Standard threads are more common, but coarse threads are better for applications where the bolt needs to be tightened and loosened frequently.
