How To Choose High-quality Screws And Use Them Correctly

 Although screws are small, they play an important role in various fields. As a special type of screw, precision electronic screws are widely used in industry and are ubiquitous in daily life. In home decoration, the total number of various screws such as doors and windows, furniture, pipelines, and household appliances can reach hundreds. Although the total value of these screws will not exceed a thousand yuan, their quality cannot be ignored.

For many years, due to the relatively simple production technology of screws and the low market entry threshold, low-quality special screws have flooded the market, making it difficult for ordinary consumers to distinguish between good and bad.

Poor quality screws are easy to fall off on furniture, and non-standard screws are not properly treated for rust prevention, resulting in rust and water leakage in a short period of time. Low quality expansion screws can easily cause safety accidents in important occasions such as chandeliers.

So how to purchase high-quality special screws?

1： Measurement of outer diameter: The outer diameter of inferior screws is significantly shorter and thinner, one circle thinner than that of qualified screws, and there is no spring washer. Expansion screws without spring washers are difficult to secure securely.

2： Observation of appearance: Genuine screws have undergone fine surface treatment, high glossiness, no sand holes, and smooth interfaces. Poor quality screws have rough craftsmanship, shallow threads, numerous burrs, varying widths of screw corners, shallow thread grooves, and uneven threads. If inferior screws are used in furniture, they can easily slip or even break, and are basically disposable products.

What to pay attention to when using screws:

1. Choose the appropriate screw: There are many types of screws, and when fixing items, the appropriate screw type should be selected. For example, fixing the license plate with anti-theft screws and fixing household appliances to the wall requires the use of expansion screws. For small items, you can choose screws, etc. When using screws, it is necessary to choose the appropriate model of screwdriver based on the groove of the screw head, as incorrect selection may cause the screw to slide.

2. Prevent screws from rusting: Screws may rust due to damp usage environments. If the screw is rusty, do not remove it with force. You can spray rust remover on the screw and wait for a period of time before using a screwdriver to remove it.
