Carriage bolts are divided into large semi-round head carriage bolts (corresponding to standards GB/T14 and DIN603) and small semi-round head carriage bolts (corresponding to standard GB/T12-85) according to the head size. Carriage bolt is a type of fastener consisting of a head and a screw (a cylinder with external threads). It needs to be matched with a nut and is used to fasten two parts with through holes.

The anchor bolts are generally made of Q235 steel, which is round and smooth. Threaded steel (Q345) has high strength, making it easier to make nuts with threads that are not smooth and round. For round anchor bolts, the burial depth is generally 25 times their diameter, and then a 90 degree hook with a length of about 120mm is made. If the bolt diameter is too large (such as 45mm) and the burial depth is too deep, a square plate can be welded at the end of the bolt, that is, a large head can be made (although there are also certain requirements). The burial depth and bending hook are both to ensure the friction between the bolt and the foundation, so as not to cause the bolt to be pulled out and damaged.

Cross flange screw, also known as cross pan head flange screw, is a multi-purpose screw. Its head is cross shaped and can be tightened with different types of batch heads. Cross flange screws are suitable for industries such as vehicle manufacturing, mechanical equipment, electrical equipment, and electronic products.

Screws are tools that use the physical and mathematical principles of the inclined circular rotation and friction of an object to gradually tighten the mechanical parts of the object. Drill tail screws are screws with self tapping drill heads at the front end of the screw. Screw is a common invention in people's production and life for thousands of years. According to its application field, it is the first great invention of humanity. Drill tail screw is a new invention in recent years, also known as self drilling screw.

The shape of a U-bolt is U-shaped, with threads on both sides that can be combined with a nut. U-bolts are mostly used to fix pipe states and sheet materials. It is commonly used in fixing water pipes, automotive leaf springs, building installations, and vehicles and ships. After fixing the object with a U-bolt, its shape resembles that of a person riding a horse, so many people refer to U-bolts as horse riding bolts. U-bolts have many material properties, which vary depending on their usage in different places.
