Bolt: Mechanical parts, cylindrical threaded fasteners with nuts. A type of fastener consisting of a head and a screw (a cylinder with an external thread) is required to be fitted with a nut for fastening the two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

The bolt manufacturer's customization is mainly divided according to the way the connection is applied: it is used for ordinary and reamed holes. According to the shape of the head: there are hexagonal heads, round heads, square heads, countersunk heads, etc. The hexagonal head is the most commonly used. Generally, the countersunk head is used where the connection is required. According to the length of the thread, it is divided into two types: full thread and non-full thread. The thread type is divided into two types: coarse teeth and fine teeth. The coarse tooth type is not displayed in the bolt symbol. Bolts are classified into 3.6, 4.8, 5.6, 5.8, 8.8, 9.8, 10.9, and 12.9 grades according to performance grades. The bolts of grade 8.8 or higher (including grade 8.8) are made of low carbon alloy steel or medium carbon steel and heat treated (quenched). + tempering), commonly known as high-strength bolts, below 8.8 (excluding 8.8) is commonly called ordinary bolts. Ordinary bolts can be divided into three grades A, B, and C according to the manufacturing precision. Grades A and B are refined bolts, and grade C is thick bolts. For the connection bolts for steel structures, unless otherwise specified, they are generally ordinary C-class bolts.

There are differences in the squareness of different grades, and the corresponding processing methods are as follows:

The bolts of 1A and B grade bolts are machined by lathe, the surface is smooth and the size is accurate. The material performance grade is 8.8, the production and installation are complicated, the price is high, and it is rarely used;

The 2C grade bolts are made of unprocessed round steel and are not accurate enough to have a material performance rating of 4.6 or 4.8. The deformation is large when the shear connection is made, but the installation is convenient, the production cost is low, and it is mostly used for the temporary connection of the tensile connection or the installation.

In summary, we can see that there are many different types of products customized by bolt manufacturers. There is always a suitable one for you.
