Common Problems Of Stainless Steel Screws In Daily Use
Stainless steel screw is an essential part of our daily life, but there are a lot of common problems in the use process, and few people know how to deal with these problems, such as the common loose, rust, fracture and other problem. Once these problems occur, the screw will need to be replaced in minor cases, and in serious cases, it will cause destructive damage to the equipment components. So how to avoid these problems? As a professional fastener manufacturer, Xinchi fastener Company lists these common problems and their prevention methods.
The anti-loose problem of Stainless steel screw
Directly speaking, anti-loosening is when the stainless steel screws are used in the product material, and will not easily fall down. This requires screws to be more tightly connected with the product material. For the stainless steel screw loose solution, there are the following two solutions.
The first method is to use the resilience of special materials, such as engineering resin materials, which have better resilience. The special material is attached to the stainless steel screw teeth, so that it and the nut or material produce mechanical friction, and then produce vibration and absolute resistance, so as to completely solve the screw loose problem.
The second method is to apply a layer of glue to the stainless steel screw thread. This adhesive is called fall-resistant adhesive, with high adherence, non-toxic and other good properties. The glue is coated on the stainless steel screw, and after it is dry, the adhesion force is super strong, which can make the stainless steel screw thread in the nut thread combination or in the product thread hole joint, produce a super fastening effect, play a super good anti-loosening effect.
The rust problem of stainless steel screws
In humid air, the attachment of dust or exotic metal particles and the condensate of stainless steel screws form a microbattery, which causes an electrochemical reaction and damages the protective film, which is called electrochemical corrosion.
In the case of water oxygen, organic juice (such as melons and vegetables, noodle soup, sputum, etc.) on the surface of the stainless steel screw, will form organic acids, which will cause corrosion to the metal surface for a long time.
The surface adhesion of stainless steel screws contains acid, alkali and salt substances (such as the splash of alkali water and limestone water in the decoration of walls), which may cause local corrosion.
If the polluted air (such as the atmosphere containing a lot of sulfides, carbon oxide, and nitrogen oxide) encounter condensate water, it will form sulfuric acid, nitric acid, and acetic acid liquid point, thereby causing chemical corrosion.
The above several cases can cause damage to stainless steel screw surface protective film, resulting in corrosion. Therefore, in order to ensure that the surface of the stainless steel screws is permanently bright, and not to be corroded, we must do cleaning, passivation, and other processing on the surface.
Xinchi fastener Company reminds you: when using stainless steel screws in daily work and life, we must pay attention to the above four points to prevent stainless steel screws from rusting.
The fracture problem of Stainless steel screws:
Generally speaking, stainless steel screws are rarely broken. Because the stainless steel screw wire is relatively hard. But under certain circumstances, stainless steel screws can still break. So what are the main reasons for stainless steel screw breakage?
The reasons for the breakage of stainless steel screws are as follows:
- The raw material quality problems stainless steel screws. If the quality of stainless steel screw wire is not good, there are a lot of impurities, which will lead to the hardness of stainless steel screws is not enough.
- The production process of stainless steel screws. For example, there may be offset or eccentric stainless steel screws and the Q value is too deep and the R position is too small.
The customer used too much force when using stainless steel screws. It is generally recommended to do a torque test on stainless steel screws first, see how much the minimum breaking force is, and then adjust the corresponding torque.
The above three reasons are the main cause of stainless steel screw breakage. There are a variety of problems with broken screws. If none of the above is the cause, you should check step by step to find the final cause.
