Service HotlineNuts are very common fasteners. Generally, the torque cannot be limited when the nut is twisted. The degree of tightness of the nut is mostly judged by the worker's experience. In this way, when the nut is over-tightened, it will lead to the destruction of the thread pair, thereby shortening the fastener. The life of the nut may even cause the bolts to be pulled off in severe cases; and the nut is too loosely screwed, which will lead to the problem of insecure fixing.
In real life, MontrealMontrealrivet nuts are used. With different specifications and different uses, many people are familiar with this tool but don't know how to use it properly. In fact, MontrealMontrealrivet nut tools have manual and transmission, and now are rarely used for manual. If you choose to use electric MontrealMontrealrivet nuts in order to improve production efficiency, which of the two is more widely used? The following describes the use of electric MontrealMontrealrivet nuts and manual nuts. How to use the manual MontrealMontrealrivet nut tool: Insert the MontrealMontrealrivet nut into the drilled installation hole with a rivet mother tool to fix the MontrealMontrealrivet nut. (1) Screw the MontrealMontrealrivet nut onto the MontrealMontrealrivet nut tool 2) Use the MontrealMontrealrivet nut tool to insert the MontrealMontrealrivet nut into the drilled mounting hole. (3) MontrealTighten the nut, and press the handles on both sides of the MontrealMontrealrivet nut tool to the direction of the middle round rod. You can only press it hard. Therefore, this pressure must be in place. It is forbidden to repeatedly squeeze the handles on both sides to damage the nut. Fastening thread in the form of inside. (4) The MontrealMontrealrivet nut tool is separated from the MontrealMontrealrivet nut: just loosen the ball head in the picture, and the tool will be separated from the nut after completely loosening.

The gasket side of the above-mentioned nut assembly is in contact with the mounting surface. When the nut is tightened, the gasket squeezes the outer cone surface to make it shrink, and the cone tip faces the same direction as the nut, thereby preventing the nut from tightening, so that the nut fixing effect is not good, and at the same time When multiple nuts need to be superimposed and fixed, two adjacent nuts cannot interact with each other, resulting in poor fixing effect.
Type 1 nut refers to an ordinary hexagonal nut with a nominal height of m ≥ 0.8D. Its type and size should meet the requirements of GB/T6170; while the height of type 2 nut is higher than that of type 1 nut, its type and size should comply with GB/T6170. T6175. There are two purposes to increase the type 2 nut: one is to obtain a relatively inexpensive nut that does not require heat treatment by increasing the height of the nut. Because D≤M16 grade 8 type 1 nuts do not need heat treatment, among grade 8 nuts, only the specifications of D>M16~39 use type 2 nuts. Obviously, type 1 nuts that do not need heat treatment cannot reach grade 9 nuts. Mechanical property requirements. Another purpose of specifying Type 2 nuts is to obtain a more ductile grade 12 nut. As the height of the nut increases, the guaranteed stress index can be achieved at a lower quenching and tempering hardness, so the toughness of the nut is increased. Classified by tooth spacing: standard teeth, regular teeth, fine teeth, very fine teeth and cross teeth. Classification by material: stainless steel hexagon nuts and carbon steel hexagon nuts, copper hexagon nuts, iron hexagon nuts. Classification by thickness: hexagonal thick nuts and hexagonal thin nuts. Classification by usage: hot melt copper nut, hot pressed copper nut, embedded copper nut and ultrasonic copper nut
