Alloy Steel Nuts Hexagon Nuts (GB6170/DIN934, GB6175), Flange Nuts (GB6177/DIN6923) Round Nuts (GB812), Small Round Nuts (GB810), American Square Nuts, American Hex Nuts (NI/MEB18.2.2), Heavy Duty Nuts (Metric, US). Specifications: 5/16-4. Nut specification editing Nut specification table is to unify all kinds of nuts in detail, and use the table to subdivide some specifications of nuts. There are many types of nuts, and there are nuts of different materials. 。 Each type of nut has different specifications, and each type of screw also has its own mechanical properties and functions.
The locking effect of the spring washer is general, and the important parts are used as little or not as possible, and the self-locking structure is adopted. For spring washers used for high-speed tightening (pneumatic or electric), it is best to use surface phosphating washers to improve their anti-wear performance, otherwise it is easy to burn out or open mouth due to friction and heat, and even damage the surface of the connected parts. For thin plate joints, spring washer construction should not be used. According to statistics, spring washers are used less and less in automobiles.
Many existing products need to use screws in the production process, especially in the field of nuclear power sluice gates, it is necessary to fill a part of the sluice gate with screws to fix the size and structure. If the fixing effect is not good, then It will lead to more leakage of water gates, waste a lot of water resources, and even cause safety accidents.
Bolt and nut fasteners are widely used fasteners, which can be used in mechanical products as well as daily craft industrial products, such as plastic packaging boxes, plastic packaging boxes, paper packaging boxes, paper packaging boxes, etc. . When bolt and nut fasteners are used in daily craft industrial products, the requirements for the degree of tightening are generally low, but they are required to be easy to install and use. When assembling the existing bolt and nut fasteners, it is generally necessary to manually twist the bolt or the nut several times until the two are tightened, which takes time and causes inconvenience in daily life. Lower, it is manifested as an increase in labor costs. SUMMARY OF THE INVENTION The main purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a bolt and nut fastener that is easy to install in view of the above-mentioned deficiencies of the prior art. The two are assembled and fastened, which is convenient to use.
