How to maintain common anchors bolts and screws?
1. Be careful and meticulous when rinsing the anchor bolts construction screws to ensure that no residue remains on the screw surface after cleaning with silicate cleaning agent.
2. The screws should be properly stacked during tempering heating to avoid slight oxidation in the quenching oil.
3. White phosphide substances may remain on the surface of high-strength screws, indicating that careful inspection is required during operation.
4. If blackening is found on the surface of the parts, it means that the heat treatment process is not thorough and the alkaline residues are not completely removed.
5. Standard parts may rust during rinsing, and the rinsing water needs to be replaced regularly.
