What are the precautions for stainless steel screws and hinge screws? What are the precautions for stainless steel screws and hinge screws?

Lock the flange in every situation. If you need to pay attention to and take measures based on all points above, including the use of coated washers, nuts (or can also initiate the use of long nuts, such as GB6170 or DIN934), in the diagonal sequence of the nuts, gradually, to twist the appropriate tightness, etc. If it is still impossible, it will often not be removed after the initial locking, and finally, you have to ask for flange locking assembly, and temporarily use carbon steel nuts before the first, Until the last temporary unlocking on the surface, when using stainless steel nuts for rust prevention, do not find a balance point between them.

Q: Is it crazy to always lock at a firm rate when using stainless steel hinge screws?

Answer: If it is the first time using or unfamiliar with the products of stainless steel hinge screws, users should consult their own stainless steel supplier for coherent characteristics. Under normal circumstances, slow lock rates can greatly reduce (and even completely prevent unintentional and occasional deadlocks). Due to the fact that heat is often generated during locking, the likelihood of locking increases as the thermal energy increases. When utilizing, the rate of locking the stainless steel screw should be lower than that of locking the carbon steel upward.

Hinge Screws 

Q: Is it locked before the first lubrication screw or nut?

Answer: If the answer is' no ', it can be initiated to use butter, molybdenum disulfide, graphite, mica, or talcum powder to lubricate the inner and outer ribs in order to reduce the occurrence of deadlock. The buckle stop (coating) is a useful lubrication method that, through the disposal of the buckle stop nut, will be like a screw cap and a layer of lubricating film between the ribs.

Q: How to choose the same material grade for hinge screws and nuts?

Answer: If so, hinge screws and nuts can be used to utilize different grades, such as 304 and 316. But it is necessary to pay attention to the selection of stainless steel trademarks to meet their requirements for rust prevention and corrosion resistance.
