What is the tolerance range of precision screws?
Advantages of anti-loose washers 1. Ensure that the clamping force of the connection is still maintained under strong vibration, which is better than fasteners that rely on friction to come from the lock; 2. Prevent the loosening of bolts caused by vibration, which no longer occurs due to fasteners related problems caused by loosening; 3. No special installation work is required, and it is easy to install and disassemble; 4. The temperature changes will not make the connector loose; 5. Durable; 6. Reusable.
Generally, we have to divide the fine thread nut and the coarse thread nut first, but in fact, no matter what kind of fine thread, coarse thread, their specifications are the same, their specifications are M3, M4, M5, M6, M8, M10, etc. . But there is another kind of hexagonal nut, which is divided into English and American, which is only a different national standard. Made in China, it is called the national standard hexagon nut
Guangdong Yueluo Hardware Industry Co., Ltd. is a kind of locking nut, which includes a nut, the bottom of which is circular, the middle is hexagonal, the top is circular, there is a bolt hole in the center, the side wall of the bolt hole is threaded, and the top of the nut is Set up several squash notches. According to the locking nut of the preferred embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the number of flattening notches is three. The three flattening gaps can be used as the focal point of the tightening tool and the clamping place of the anti-loose gasket bayonet, and the structure is simple and can be formed by die stamping at one time.
Yueluo - a screw and nut disassembly tool for a narrow space, including a sleeve rod, a sleeve rod vertically arranged at one end of the sleeve rod, a connecting rod for fixedly connecting the sleeve rod and the sleeve rod, and a sleeve rod located at the end of the sleeve rod. The connecting rod in the axial through hole of the sleeve rod, the connecting rod located in the axial through hole of the sleeve rod, and the bearing for fixedly connecting the sleeve rod and the connecting rod and making the connecting rod rotate stably in the sleeve rod , and a sleeve head arranged at one end of the connecting rod, the connecting rod and the adjacent end of the connecting rod are provided with gears and the two gears are vertically meshed, so that when the external force drives the connecting rod to rotate, the force passes through The two gears and the connecting rod are transmitted to the sleeve head, thereby driving the screw or nut in the sleeve head to rotate;
