There are many kinds of nuts. Now let's talk about the hydraulic nuts in detail. What are their performance advantages?
The hydraulic nut is an advanced bolt fastening system, which has the same working principle as the hydraulic stretcher. It is mainly used for the fastener assembly in narrow space and the fastening of heavy load vibration machinery. It has reformed the traditional fastening method, using the hydraulic system to make the fastening bolt through pure axial tension, accurately achieve the predetermined load, and then mechanically lock on the fastener, so as to complete the fastening work. Because the screw is only subjected to pure tensile force, the pre tightening force of bolt pair can be increased by 20% - 30%.
