Studs usually require cosmetic treatment. There are various types of bolt appearance treatments. Commonly used are electroplating, blackening, oxidation, phosphating and electroless zinc flake coating. However, electroplated fasteners account for a large proportion of the practical application of fasteners. This is especially true in industries and categories such as automotive, tractor, home appliances, instrumentation, aerospace and communications.

However, for threaded fasteners, it is not only necessary to have a certain anti-corrosion ability in use, but also to ensure the interchangeability of threads, which can also be referred to as screwability here. In order to meet the dual application performance of "corrosion protection" and "interchangeability" required in the operation of threaded fasteners, it is necessary to formulate special plating specifications.

Studs require fixing equipment and machine tools. Of course, the process is relatively simple. There are mainly the following steps: 1. Need to draw materials. Material stretching is the correction of the deformed material by a material stretching machine. After this process, the next process can be stopped. The next step is to use a cutting machine to cut the straightened long stock to the customer's desired length according to the user's requirements. This completes the second process.

The third step is to put the cut material on the thread rolling machine and roll out the thread. Of course, ordinary studs are machined here, if other requirements are required, other processes are required. Well-known bolts are those with larger diameters. According to this statement, the diameter of a screw is much smaller than that of a bolt. Studs do not have heads, some are called studs. Studs are threaded on both ends, unthreaded in the middle, and have a polished rod in the middle.
