GB/T 889.2 lockable nut has the following 3 advantages: First, excellent anti-vibration performance: when the thread is tightened, the crest thread of the lockable nut and bolt tightly enters the 30° wedge-shaped slope of the nut and is clamped, and the normal force exerted on the wedge- shaped slope is the same as the bolt's normal force. The axis forms an included angle of 60° instead of 30°. Therefore, the normal force generated when the anti-loose nut is tightened is much larger than that of the ordinary standard lock nut screw, and it has a great anti-loose and anti-vibration ability. Second, the wear resistance and shear resistance are strong: the 30° slope of the nut thread bottom can make the lockable nut locking force evenly distributed on the threads of all the teeth. Lock nut pack can better solve the problems of thread wear and shear deformation. Third, the repeated use performance is good: a lot of use shows that the locking force of the locking nuts and bolts will not decrease after repeated tightening and dismantling, and the original locking effect can be maintained. GB/T 889.2 Lockable Nut Specifications  GB /T 889.2 Lockable Nut And Bolt GB /T 889.2 - 2016 Prevailing Torque Type Hexagon Nuts(With Non-Metallic Insert), Style 1-Fine Pitch Thread If you need any kinds of nut and bolt supply, please contact us, as one of the most professional fastener manufacturers, Datian is willing to offer you high quality products.

GB/T 12868 Black T Nuts Features: The principle of the inclined plane is adopted, the deformation of the inclined plane is integrated to form a thread, and then it is rotated into a parallel motion, the lead screw is rotated once, and the bolt and t nut is moved to a pitch. GB/T 12868 black hex t nut can effectively save time and effort.

Dhina railway fastener are widely used in urban rail construction. In recent years, rail fasteners have been put into the field of railway and steel structures, and they are very popular and sought after Rail joints of railways are the source of vibration. In order to overcome this source of vibration and reduce the occurrence of rail joint diseases, the use of railroad track bolts and nuts is the best choice. They can eliminate the diseases of rail joints and increase the resistance of joints. Although the construction of railways is inseparable from the role of railway fasteners, not all specifications and types of railway bolts and nuts are suitable for railway construction. The strength of some ordinary railway fasteners cannot adapt to the vibration of high-speed rail, railway, and subway. All rail transportation requires high- strength railway fasteners. As railway construction continues to increase, the demand for high-strength railway fasteners around the world will also rapidly increase. As one of the leading railway fastener factories in China, DT can provide you with quality railway fasteners at great prices. Feel free to contact at any time. If you need any kinds of quality fasteners, please contact us, as a professional fastener factory, Datian is willing to offer you high quality products.

Boiler steel plate is one of the very key materials in boiler manufacturing, mainly refers to the hot rolled special carbon steel and low alloy heat resistant steel medium thick steel material used to manufacture boiler shell, pot drum, box end cover, hanger and other important parts. 16MnDR is a kind of steel plate for cryogenic pressure vessel. 16Mn -- indicates that manganese content in steel plate is about 0.16%, D- indicates low temperature, R- indicates pressure vessel. (Usually, steel with a high content of a certain chemical element needs to be marked in the material, for example, 1.6% manganese is written as 16Mn, 16MnDR is used for -40 degree pressure vessel steel plate.
