What is the tolerance range of precision screws?
There are many types of rivets, including dome head, flat head, blind rivet and so on. When riveting parts, they will have uneven force and affect the quality of riveting. Some rivet caps are too thin to easily affect the quality of riveting. Some rivets have poor tightness of riveted parts when riveting. Therefore, both the structure of the rivet and the tightness of the riveting need to be considered, so as to enhance the quality of the rivet fastening.
The use of stainless steel screw lines: The hardness of stainless steel screw lines causes them to have different uses. Generally, they are used as small screws in life, but also as car screws and compression screws. They are widely used in normal life. Types of stainless steel screw lines: In appearance, screw lines are generally divided into fog surface spring lines and bright surface screw lines. The hardness of matte surface screw lines is higher than that of bright surface screw lines. For products with low appearance requirements and relatively high elasticity requirements. Paper, oxalic acid, fertilizer and other production equipment; photography, food industry, facilities in coastal areas, ropes, CD rods, bolts, nuts.
As we all know, screws and nuts are widely used in various mechanical equipment as connectors, so that the mechanical equipment can be easily disassembled, but for equipment whose internal structure needs to be kept secret, it generally does not need to be disassembled after assembly. The nut can be easily dismantled, leaving equipment that needs to be kept secret of the internal structure from being kept secret.
Screws are very small screws used for indispensable industrial necessities in daily life, such as cameras, glasses, clocks, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.; large screws are used for engineering, construction, and bridges; Transportation equipment, airplanes, trams, automobiles, etc. use large and small screws together. At present, in the machine assembly production line, when the flat washers, spring washers and screws are matched during the screw assembly process, the flat washers, spring washers and screws are easy to fall into the product due to their small size, resulting in low screw matching efficiency. If there are flat washers, spring washers, screws, etc. that fall into the product and are not found in time and left inside the product, it may cause damage to the machine structure, and even cause casualties in serious cases.
