Types of hex bolts

Hex bolts are threaded fasteners with a hexagonal head, designed to be used with a wrench or socket for tightening. There are several different types of hex bolts available, each with their own unique features and advantages. Some common types of hex bolts include:

1. Fully threaded hex bolts: These bolts have threads along the entire length of the shaft, allowing them to be used in situations where the full length of the bolt is needed for securing materials together. Fully threaded hex bolts are commonly used in construction and landscaping projects.

2. Partially threaded hex bolts: These bolts have threads only along a portion of the shaft, with the remainder of the shaft being smooth. Partially threaded hex bolts are often used in applications where a precise amount of threading is required, such as in machinery or automotive assemblies.

3. Hex cap screws: Hex cap screws are typically stronger and more durable than regular hex bolts, thanks to their thicker construction and higher tensile strength. These bolts are commonly used in heavy-duty applications, such as in structural steelwork or industrial equipment.

4. Flange hex bolts: Flange hex bolts have a built-in washer-like flange beneath the hex head, providing a larger surface area for distributing the load. This helps to prevent the bolt from loosening under heavy vibrations or torque. Flange hex bolts are commonly used in automotive and machinery applications.

5. Hex lag bolts: Hex lag bolts have a pointed tip and are designed to be used in wood or other soft materials. These bolts are commonly used in construction projects, such as for securing wooden beams or framing structures.

Overall, the type of hex bolt you choose will depend on the specific requirements of your project. It’s important to select the right type of bolt for the job to ensure a secure and reliable connection.
