What is the tolerance range of precision screws?
Bolts with low hardness and strength. Generally, ordinary bolt materials are produced with ordinary screw wires. The hardness, strength, tensile strength and torsion force of ordinary bolt materials are not very high. High-strength bolts generally refer to high-strength bolts. Its own screw material, bolt material, and bolt material are relatively good, and the hardness is relatively high, and after the production is completed, the bolts will be hardened. Make the bolts meet the grade strength requirements of high-strength bolts.
Guangdong Yueluo Hardware Industry Co., Ltd. discloses an eccentric special-shaped rivet, which has a simple structure and is inexpensive to manufacture. The eccentric shaped rivet includes a cylindrical head and an eccentric polished rod. The diameter of the cylindrical head is larger than that of the eccentric polished rod. The eccentric polished rod is arranged at the lower end of the cylindrical head, and the axis of the eccentric polished rod is not the same as the axis of the cylindrical head. on the same straight line. The eccentric special-shaped rivet has low manufacturing cost and is easy to realize automatic assembly.
Flat washers are frequently used in mechanical connections. They are usually placed between the nut or screw head and the connected parts to prevent the screw or nut from loosening during use. The upper and lower end faces of conventional flat gaskets are mostly smooth planes, with a single structure and poor compressive capacity. When assembled with a nut or screw, the pressure on the flat washer is increased, and when it is closely rubbed with the nut or screw, it is prone to breakage, which greatly affects the quality of the product.
The existing combination screws and accessories are individually processed and then handed over to the customer for assembly. This method is prone to assembly problems, and the combination screws and accessories need to be marked with identification marks, which increases the production cost.
