Description

Technical Field

[0001] The utility model relates to the technical field of fastening bolts, in particular to a wear-resistant fastening bolt. Background Art

[0002] Fastening bolts are a very common fastener used to connect and fix various mechanical and structural components. This type of connection is a detachable connection because the bolt can be repeatedly tightened and loosened to tighten or separate the connection. Bolts usually consist of two main parts, the head and the threaded screw. They are widely used in daily life and industrial manufacturing and are often called the rice of industry.

[0003] Existing fastening bolts do not have the advantage of wear resistance. Since the hexagonal screw head of traditional fastening bolts will be exposed to the air for a long time after installation, the hexagonal screw head will inevitably wear out. Long-term wear will cause the hexagonal screw head to corrode, making it difficult to remove the fastening bolt, affecting the normal operation of the connecting parts and ultimately reducing the service life of the fastening bolt. Therefore, we propose an anti-wear fastening bolt to solve this problem. Utility Model Content
