Common problems and solutions of stainless steel screws in use

Common problems and solutions in the use of stainless steel screws

1. Loose stainless steel screws

Stainless steel screws are used on product materials to prevent them from falling off. Screws need to be more tightly connected to the product material. There are two solutions for loosening stainless steel screws:

1、 Using special materials with resilience, such as engineering resin materials, which have good resilience. Install it on the stainless steel screw teeth system. Create mechanical friction between it and the nut or material. Vibration and resistance were generated. Resolve the issue of loose screws

2、 Apply a layer of glue on the stainless steel screw teeth thread, known as glue. This type of glue is called anti breakage glue. This adhesive has excellent properties such as high adhesion. This adhesive is suitable for stainless steel screws and has strong adhesion after drying. It can cause excessive tightening of stainless steel threads in nut thread combinations or in product threaded hole joints. It has a good effect on preventing loosening

2. Rust problem of stainless steel screws

1. Dust or foreign metal particles from attachments can condense with the stainless steel screw in humid air, and the two will connect into micro cells, causing electrochemical reactions and damaging the protective film, which is called electrochemical corrosion.

2、 The surface of stainless steel screws is attached with organic (based on actual reports) juices (such as vegetables, noodle soup, sputum, etc.), which corrode the metal surface for a long time when exposed to water, oxygen, organic (based on actual reports) acids, and organic (based on actual reports) acids

3、 The surface of stainless steel screws adheres to substances containing acids, alkalis, and salts (such as alkali water and lime water splashing on decorated walls), causing local corrosion

4、 In polluted air (such as atmosphere containing a large amount of sulfides, carbon oxides, and nitrogen oxides), condensed water forms sulfuric acid, nitric acid, and acetic acid droplets, causing chemical corrosion
