Let’s now talk about how it is made screws (phosphated or galvanized), how to control the quality of the self-tapping screws for drywall, wood and metal screws for and how to distinguish quality from poor-quality screws. And most importantly how to find out whether the factory can produce high quality screws before you place your order with them.
Purchase of raw materials
Let’s start with the fact that for the production of screws (for metal, wood, drywall) is commonly used two kinds of low-carbon steel: 1022a and Q235. Steel is supplied to the plant in the bays in the form of the desired wire diameter.
This is a Chinese steel grade, the numbers 235 mean index of the yield stress, which is equal to 235 Mpa for this steel. This type of raw materials used for cheap self-tapping screws that are not thermally processed. We do not recommend that you buy such screws wholesale in China, but all the same if you need oochen low price, then you can consider this option. However, the screws of the q235 steel screw does not turn into something harder than wood. So be prepared.
This is the most common type of steel for the production of self-tapping screws. Screws made of this steel must be tempered, which greatly increases the strength and reliability of screws, but at the same time increases the cost of production. This kind of self-tapping screws may be used for working with metal. So if you are planning to buy screws wholesale in China, then you should definitely choose this kind of steel, which is currently considered the best ratio of price and quality.
If you are not sure of which produces steel screws your supplier, you can pay attention to the markings on the coils of wire that are in stock. On labeling, you should see the steel grade. If the marking of the bay you have not seen, that is a serious reason to think about the reliability of the manufacturer.
