Because the stainless steel bolt is used more frequently in daily life, so there are more problems, summed up this period of time customers to consult me more frequently, the following to explain the anti-loose, rust and fracture problems, so that you can maintain and extend the use of stainless steel bolt time.

Locking problems

Many customers in the purchase of inappropriate stainless steel screws or improper use of the case, will produce the phenomenon of screw loosening.

The following anti-loosening can effectively avoid these problems, so that the screws are more tightly connected to the product material, and will not slide easily:

First, according to the resilience of special materials, such as engineering resin materials, it has good resilience.

Attach it to the stainless steel screw teeth. Make it with the nut, or material products for mechanical friction. Generate vibration and resistance. Solve screw loose problem.

Two, in the process of use, in the stainless steel screw thread coated with a layer of glue, the so-called dispensing. This kind of glue is called drop resistant glue.

This kind of adhesive has good properties such as high adhesion. The glue is applied to stainless steel screws and sticks well when it dries.

Can make the stainless steel screw thread in the nut thread combination, or in the product thread hole after the joint, produce super fastening effect. Play a good role in preventing loose.

Rust problem

Stainless steel bolts themselves will not rust, but in the air may contact with other substances reaction resulting in rust, Xiaobian summed up a few easy to rust environment, you can try to avoid:

A, if your screw is used in relatively humid air, there are dust or similar metal particles around the attachment, attachment and stainless steel screw condensate, the two connected into a micro battery, triggered an electrochemical reaction, the protective film is damaged, called electrochemical corrosion.

Two, when the surface of the stainless steel screw adheres to organic juice (such as vegetables, noodle soup, sputum, etc.), in the case of water and oxygen, constitute organic acids, long time is the corrosion of organic acids on the metal surface.

Three, when the stainless steel screw surface adhesion contains acid, alkali, salt substances (such as decoration wall alkali, stone ash water splashing), cause local corrosion.

Four, in the polluted air (such as the atmosphere containing a large number of sulfide, carbon oxide, nitrogen oxide), condensate water, the formation of sulfuric acid, nitric acid, acetic acid liquid point, causing chemical corrosion.

Fracture problems

First, the problem of the manufacturer. The quality of the wire used in the production of the stainless steel bolts you bought is not good. There are a lot of impurities and impure, which leads to the insufficient hardness of the stainless steel screws.

Two, the production process problems, such as eccentric head stainless steel screws, as well as production and manufacturing when the Q value is too deep and the R bit design is too small.

Three, the use of the process of the problem, may be because you in the use of the process, the force is too large.

It is generally recommended to test the torque of stainless steel screws to see how much the small breaking force is, and then adjust the corresponding torque.
