China Bolts Manufacturers introduces the maintenance precautions for fasteners:
1. Apply oil to protect the surface. Lijia fasteners have also done this step when they leave the factory. The tools for cleaning iron products are rags and stainless steel oil. The stainless steel oil is poured on the rag and then wiped back and forth on the stainless steel items until it is full.
2. If the fasteners that have been used for a long time are re-maintained, you can wipe them with a clean dry cloth until the stainless steel oil is wiped clean and the stainless steel items become bright and stopped. If you still find the phenomenon of blooming, you should immediately. Repeat the above steps until the wiping stops.
3. For any iron product, a rust removal operation will be carried out before cleaning. The emulsion cleaning agent is a concentrated pure oil product, which becomes a white milky liquid after being diluted in water. This cleaning agent leaves a rust-resistant film on the fastener surface while dissolving dirt on the fastener surface. Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with an external thread), which needs to cooperate with a nut to fasten and connect two parts with through holes. Strength grades are differentiated based on mechanical properties.
