The advantage of the combination screw is that it is easy to use, saving the time of matching the manual ejection pad, and also improving the screw efficiency of some electronic and electrical manufacturers. The function of the combination screw is also very simple, that is, to connect and fasten products. Because it is a flat pad used to rub the teeth on the screw, it does not need to be matched with the flat pad when used. In use, another particularly important role of the screw combination is the anti-loosening effect.
Advantages of combination screws:
1. Pre-assembled components ensure faster assembly speed.
2. Reduce failures caused by human error, improper assembly or forgetting to install anti-loosening washers;
3. Maintenance and repair can be carried out in inaccessible or limited areas;
4. Easy to assemble products of minimum size;
5. Easy and quick disassembly, difficult to remove loose washers, especially from buried holes.
6. Reduce the number of goods, optimize inventory and logistics, and save costs.
Combination screw precautions:
1. Iron combination screws can be sucked by magnets, while stainless steel combination screws are difficult to suck.
2. Environmentally friendly and non-environmentally friendly combination screws cannot be seen with the naked eye. It requires mechanical testing. It cannot be judged by the naked eye or air.
3. The specifications of the combination screw are determined according to national standards.
4. How many hours does the salt spray of the combination screw need to be measured by a salt spray machine.
