Description

A high-strength corrosion-resistant bolt assembly Technical Field

[0001] This utility model relates to the field of bolt technology, and in particular to a high-strength corrosion-resistant bolt assembly. Background Technology

[0002] Bolts are the core component of bolt assemblies, mainly consisting of a head and a shank. There are many types of bolts. According to the head shape, they can be divided into hexagonal head bolts, square head bolts, countersunk head bolts, and socket head cap screws, etc. According to the thread type, they can be divided into fully threaded bolts, semi-threaded bolts, and coarse thread bolts. According to their uses and functions, they can be divided into high-strength bolts, expansion bolts, anchor bolts, T-bolts, and double-ended bolts, etc. According to their materials, they can be divided into carbon steel bolts, stainless steel bolts, and alloy steel bolts, etc. These different types of bolts each have their own characteristics and are suitable for different application scenarios.

[0003] The following problems exist: In the current usage environment, if bolts are exposed to open air for a long time, they are often affected by surrounding environmental factors, such as moisture and dust. These factors can cause oxidation reactions on the bolt surface, resulting in rust. This rusting not only shortens the overall service life of the bolts, but also reduces their tightening effect due to the reduction of surface friction during use, thus affecting the safety performance of the bolts.
