Tips for choosing screws

 Consumers, as non-professionals, how to protect their own interests to ensure that they do not buy bad screws, screw manufacturers share some tips for selecting screws, hoping to help everyone choose to buy screws.
1. The screw manufacturer tells you that the surface of the good screw is fine and smooth, smooth and regular, and the bad edge is not polished, and there are burrs. If this is the case, try to buy a smooth and good screw;
2. Good quality screws have a long service life. You can ask the manufacturer how much its service life is to decide whether to buy it;
3. The screws shared by the screw manufacturers can fasten objects, machines, and work closely with other things.
How to judge the quality of stainless steel screw manufacturers?
The screws produced by stainless steel screw manufacturers are widely used in electrician, electrical appliances, lighting and hardware building materials manufacturing industries to make them beautiful, strong, safe and stable. So how do you judge that the screws produced by stainless steel screw manufacturers are of good quality?
1. A good time for establishment is important, because you have been doing it for a long time and have rich experience. If you want to buy good stainless steel screws, you may choose a screw manufacturer with a longer age;
2. Understand the company you want to choose from the perspective of peers or customers, so that you can think about whether to choose this one;
3. You can start with the customers who cooperate with stainless steel screw manufacturers to find out whether their after-sales service is possible.

Is the material of stainless steel screws magnetic?

There are many types of materials for making stainless steel screws, and they can be divided into several categories according to the structure at room temperature: austenitic type: such as 304, 321, 316, 310, etc.; martensite or ferrite type: such as 430, 420, 410 Wait;   Austenite is non-magnetic or weakly magnetic, while martensite or ferrite is magnetic. Due to component segregation or improper heat treatment during smelting, a small amount of martensite or ferrite in austenitic 304 stainless steel will result. In this way, 304 stainless steel will have weak magnetic properties.     After 304 stainless steel is cold worked, the structure will also be transformed into martensite. The greater the degree of cold working deformation, the more martensite transformation and the greater the magnetic properties of the steel. Like a batch of steel belts, Φ76 tubes are produced without obvious magnetic induction, and Φ9.5 tubes are produced. Because the bending deformation...

How to distinguish between high-strength nuts and ordinary nuts?

What is the difference between high-strength nuts and general nuts, in fact, you only need to understand their standards and other characteristics to easily distinguish them. The so-called high-strength nut is a special bolt with high strength and high fatigue resistance used in special equipment or engineering. Of course, generally high-strength nuts are used with high-strength bolts to achieve better application. We generally see that many bolts with M heads in the market are ordinary nuts, not high-strength nuts. The calibration side of the general hexagonal head nut is the following pattern M30, and M30 indicates the thread standard, that is, the inner diameter of the thread is 30mm. Grade 10 indicates the functional grade of the bolt, and tZn is the surface treatment method. Other types of bolts also have their own expressions, but generally threaded bolts have to use the original functional grade of "M": The functional level of the nut is divided into 3, 4, 4, 5, 5.8, 6...

How to prevent stainless steel screws from rusting

 Analysis of the causes of rusty hardware screws: 1. When the electroplating factory is electroplating hardware screws, the drying is not done, resulting in residual water vapor. Or, after drying, condensate is formed during packaging. Dongguan Electronic Screw Factory introduces to you, it causes chemical reaction, produces bad occurrence, and causes hardware screw to rust. 2. Stored in a humid place for a long time. Over time, the hardware screws will slowly be corroded and oxidized, causing serious rust. 3. When electroplating hardware screws, the electroplating is poor, and the electroplating layer is too thin. Cause rust. All in all, analyze the reasons from four aspects.   The four directions are: 1. Storage environment 2. Types of electroplating 3. How to save 4. Use environment. Therefore, we must pay attention to the key points in the use of stainless steel screws: 1. The surface of the stainless steel screw adheres to the organic juice (such as melon, vegetable, nood...
