1. When using stainless steel screws, pay attention to first checking whether the screw threads are complete, whether there are residues or stains, etc.

2. The fasteners can be lubricated before use. It is recommended to use butter, molybdenum disulfide, mica, graphite or talc for lubrication. At present, wax dipping is commonly used for lubrication and anti-locking.

3. When choosing stainless steel nuts to be used in conjunction with stainless steel screws, you must choose the matching connector products.

4. The tensile strength of the stainless steel screw and the load of the matching nut must meet the mechanical properties of the object.

5. The use of washers can effectively prevent the problem of over-locking.

6. Do not operate the stainless steel screw too fast and the operation force should not be too strong.
