Description

[0002] Mechanical fasteners are commonly used in various equipment in the fields of electronics, machinery and chemical industry to connect and fix various components and structures. In some cases, these equipment may be applied in relatively harsh external environments, resulting in different damage conditions on the surface, thus causing problems such as loose structure and unfavorable disassembly. After retrieval, the fastener applied to a corrosive working environment disclosed in the patent application No. CN200920210008.5 records that a hard or soft corrosion-resistant protective layer is coated on the external surface, and the protective layer is made of PVC material and is a film-like material.
