How much do you know about screws? Let's follow the editor of HDG Slotted Head Screw manufacturers for a brief understanding!
The screw fastening device includes a base and a screw, the base is provided with a screw mounting hole, the screw mounting hole is provided with a bearing platform, and the slope of the slope of the bearing platform is the same as the slope of the screw countersunk head. A hinge cup is also arranged between the screw and the hinge cup. The hinge cup is provided with a mounting hole that matches with the screw mounting hole of the base and can accommodate the countersunk head of the screw. The mounting hole is also provided with a bearing platform. The length of the mounting hole is greater than the diameter of the screw countersunk head, and the width of the mounting hole is the same as the diameter of the screw countersunk head. Since the base is provided with a platform, it is more beautiful. The mounting table has a certain slope, and the screws have a certain space on both sides of the installation hole, so the screws have a certain adjustment space, but they are fast enough, which greatly prolongs the service life of furniture or other products.
