1. When using stainless steel screws, do you always lock nuts with fixed speed?
If it is the first time to use or unfamiliar with stainless steel screw products, please consult your supplier about the relevant characteristics of stainless steel. In general, slowing the speed of locking can dramatically reduce (or even eliminate) the chance of locking up. Because heat often occurs in locks, the chance of locking up the heat increases as heat increases. When used, the speed of the stainless steel screw should be lower than the speed of the carbon steel locked.
2. Do you lubricate the screw or nut before locking?
If the answer is "no", it is recommended to use butter, molybdenum disulphide, graphite, mica or talcum powder to lubricate the internal and external tooth lines to reduce lock and death. It is also an effective way to lubricate, and the suspended nut will be like a layer of lubrication between the nut and the screw.
3. Do you choose the same type of screw and nut?
If the answer is yes, you can recommend using different levels of screws and nuts, such as 304 and 316. But note that the selected stainless steel grades are also in line with their own corrosion resistance.
In addition, the lock flange is a case of * frequent locking. Assumes that you have pay attention to and in accordance with the above points, including the use of the washer, nut on the diagonal order, slowly, in order to properly tightness, etc., if still can't solve, often in advance after the lock can't unload down, after *, only good please in advance to lock device first temporarily use carbon steel nut, flange plate until * after formally locked again when using stainless steel nut, in beautiful for a balance between resistance to rust and not locked.
