Description
Screw is the most common fastener in life, which is used in all aspects of life. Although the screws look simple, they contain many kinds of materials, heads, grooves, threads and prices. Therefore, as a manufacturer of non-standard special-shaped screws, when customers need to customize non-standard special-shaped screws, they must check the information provided by customers and the customization needs of non-standard special-shaped screws before starting production, so as to avoid considerable losses. The non-standard screw can be customized according to the requirements of the company and the requirements of the goods, saving the company's product development and design time and improving work efficiency.

Quality Inspection
I believe that we are no strangers to screw fasteners, and we can also use them in our daily life. The screw is small, but its role is not small, so its quality cannot be ignored when buying screws. Next, the screw manufacturer will talk to you about how to find good quality screws?
First of all, look at the appearance of the screws. Good screws have high glossiness after surface processing, and the joints are not as smooth as those with sand holes. Poor screws have rough processing, many burrs, difficult landing angles, shallow thread grooves, and uneven threads. Such poor screws are easy to slip or even crack when added to furniture. Basically, they can't be reused once.
Measure the outer diameter of the screw. The outer diameter of the inferior screw will be different from the actual size. The size is not fine enough, so it may not be easy to buy it back.
According to the production scale of the screw manufacturer, many people usually go to the hardware store to buy screws, but some screws are difficult to buy in the hardware store, so we need to find the manufacturer to customize them. We need to find a screw manufacturer with large scale and sufficient production experience. The quality of the customized screws need not be worried.
We are a screw manufacturer with 30 years of production experience, mainly engaged in a series of non-standard screw customization, widely used in various industries. If you have screw procurement needs, you can contact us!
