Bolts and nuts are common types of mechanical connectors, and they achieve fastening through the cooperation of threads. Different types of bolts and nuts are suitable for different occasions, and several common bolts and nuts will be introduced below.

1. Hex Bolts and Nuts: These are the most commonly used types of bolts and nuts in construction and engineering applications. They have a hex head and tighten with a wrench.

2. Carriage Bolts and Nuts: These bolts have smooth domed heads and square shanks that prevent them from turning when tightened. They are commonly used in woodwork and furniture assembly.

3. Lag Bolts and Nuts: These are heavy-duty bolts used to secure large objects to wood or other materials. They have a hex head and a partially or fully threaded shank.

4. Eyebolts and Nuts: These bolts have a ring head and can be used to attach a rope, cable, or chain. They are commonly used in rigging and lifting applications.

5. U-Bolts and Nuts: These bolts have a U-shaped head and are used to secure pipes, tubes, or other cylindrical objects to surfaces. They are commonly used in plumbing and automotive applications.

6. Studs and Nuts: These bolts have a threaded rod without a head and are used to hold two objects together by threading a nut onto the end of the rod. They are commonly used in flange connections and piping systems.

7. Allen bolts and nuts: These bolts have a cylindrical head with a hex socket and are tightened with an Allen wrench. They are commonly used in machinery and equipment assembly.

8. T-Bolts and Nuts: These bolts have a T-shaped head and are used to secure an object into a T-slot on a surface. They are commonly used in woodworking and metalworking applications.

9. Flanged Bolts and Nuts: These bolts have a flanged head to distribute the load over a larger surface area. They are commonly used in automotive and industrial applications.

10. J-Bolts and Nuts: These bolts have a J-shaped head and are used to secure objects to surfaces by threading a nut onto the end of the bolt. They are commonly used in architectural and engineering applications.

In short, different types of bolts and nuts are suitable for different occasions, and choosing appropriate bolts and nuts can ensure the safe and stable operation of mechanical equipment.
