HUA Huachang Screw Factory Explains How to Use Hexagon Socket Screws

HUA Huachang Screw Factory Hexagon Screw Correct Use Method

We know that screws with larger specifications are generally hexagon socket screws or external hexagon screws. Hexagon socket screws have more functions. No matter how good the fasteners are, they may loosen after the use time. The following is the use of hexagon socket. Explain the common problems when bolts.

Hexagon socket bolts are used for fastening. They are often subjected to vibration and vibration when installed on machinery. Therefore, some hexagon socket bolts may fall off. In order to avoid this phenomenon, we need to adopt some anti-loosening treatments. There are many ways to prevent loosening. Methods:

1. It is common to add a suitable spring washer between the hexagon socket bolt and the workpiece. The function of the spring washer is to increase the pressure through repulsive force, thereby improving the anti-loosening effect of the hexagon socket bolt (fixing screws are recommend used here, which is easy to install).

2. HUA Huachang screw manufacturers make drop-resistant adhesive on the thread tail of hexagon socket screws. This anti-loosening method is mostly used on small screws. The adhesive on the thread has good viscosity performance, effectively adheres to the thread surface, and has a thin thickness. After the threaded hole is tightened, it can achieve a good anti-loosening effect.

3. When used in places where the hexagon socket screws are not removed, after the screws are installed, the screws can be welded to the installation place, which can have a very good anti-loosening effect, but the hexagon socket bolts used in this way cannot be removed again. To use.

Installation and use requirements of self-tapping screws

According to the standard specifications, countersunk self-tapping screws are made of metal materials, also known as flat head screws. They are currently used in the fields of electronic machinery, digital products, decoration and electrical equipment. Then, how to use countersunk self-tapping screws? What are the precautions for use? Now for everyone to summarize.

HUA Huachang screw manufacturers use countersunk self-tapping screws:

Generally speaking, after installing the countersunk self-tapping screws, the appearance of the parts is flat and there is no protrusion. According to this, the firmly fixed parts are divided into two types, thin and thick. The thickness refers to the thickness of the part and the countersunk head. The relative ratio of the thickness of the tapping screw, the former needs to be larger than the latter. After tightening, some screws are on the outside, but it should be noted that the countersunk screws must be tightened.

In addition, when comparing the thickness of the part and the thickness of the head of the countersunk self-tapping screw, the former is smaller than the latter, which is another situation. Many mechanical equipment have sheet metal parts, for example, the connection between the equipment and the sheet metal cover, And the connection of the box body and the door of the box body, etc., due to the small thickness of the fastening parts, a conical hole is formed in the threaded hole, the screw head is not pressed on the sheet metal, but the bottom of the screw and the front end of the screw hole are squeezed from each other. Because of this, we sometimes feel that the screw is tight, but the sheet metal is really not tightened.
