Hex Nut Wholesaler Introduces The Use Process Of Hexagon Bolts


Hexagon bolts are fasteners composed of heads and screws (cylinders with external threads). It needs to be matched with a nut to be used as a fastener to connect two parts with through holes. Hex Nut Wholesaler introduces the requirements for the use of hexagonal bolts:

1. Select the product correctly: Before use, please confirm whether the mechanical properties of the product meet the requirements of use, such as the tensile strength of the hexagon socket bolt and the load of the nut. The length of the hexagon socket screw should be selected appropriately, and the screw must be selected according to the 1-2 pitch of the nut after tightening.

2. Before use, please check whether the threads are rough and whether there are iron filings or dust between the threads. These things often lead to lockups.

3. Fasteners can be lubricated before use: it is recommended to use butter, molybdenum disulfide, mica, graphite, or talc for lubrication. At present, it is common to use wax dipping lubrication treatment to prevent locking.

4. Pay attention to the method of use:

(1) The speed and force of screwing in are appropriate, not too fast or too big. Use a torque wrench or socket wrench as much as possible. Avoid using adjustable wrenches or electric wrenches. Too fast will cause the temperature to rise rapidly and cause a lockup.

(2) In the direction of applying force, the nut must be tightened perpendicular to the axis of the screw.

5. The use of washers can effectively prevent the problem of over-tightening.

6. Fasteners made of stainless steel, aluminum alloy, and titanium alloy often lock or bite. These metal alloys have anti-corrosion properties. When the surface is damaged, a thin oxide layer is formed on the metal surface to prevent further corrosion. When the stainless steel fastener is locked, the pressure and heat generated between the teeth will destroy the oxide layer, which will cause blockage or shear between the metal threads, which will lead to adhesion. When this phenomenon continues, the stainless steel fasteners will be completely locked and can no longer be removed or locked.

Subconsciously, we all think that stainless steel screws will not rust. In fact, it is not. In harsh environments, stainless steel screws will rust after being corroded. So rust is actually a relatively common situation, but we are When using stainless steel screws, most of them are used indoors or on some electrical equipment. The working environment is better. There is no pollution from seawater and a strong acid atmosphere. The probability of rusting is relatively low, so rusting is seen. It will be less.

We can only say that the corrosion resistance of stainless steel screws is particularly good. It has strong corrosion resistance to ordinary atmospheric environments, but it will still rust over a long period of time when used in coastal areas. It is this difference in the use environment that requires a necessary understanding of some basic properties of stainless steel screws in order to use stainless steel screws reasonably and effectively. Under different temperature and temperature conditions, we can choose different stainless steel screws, such as 304 stainless steel screws or 316 stainless steel screws.

2H Heavy Hex Nuts Manufacturers introduced that the anti-corrosion of stainless steel screw material mainly depends on the content of some elements in the material itself to resist atmospheric corrosion. The structural changes of the improved material can also resist corrosion in theory, but stainless steel screws are standard parts. In the case of mass production, it is not feasible to modify metal materials.

Because when we use stainless steel screws, we must pay attention to some places. For the stainless steel screws that are installed on the spot, they must be stored in a clean and ventilated place. When installing, pay attention to whether there are stains in the teeth of the stainless steel screws. Such stains can become a source of corrosion as long as they are outdoors. Pay attention to temperature changes during installation. If the temperature difference is too large, water vapor will be generated. At this time, you should not fight for installation. You should first place the screws to dry before installing, so as not to seal the water vapor at the thread.

In fact, the rust prevention of stainless steel screws mainly depends on the protective film layer on the surface of the material. This protective wax is similar to an electroplated layer of carbon steel bolts. It is this protective film that isolates the metal structure layer from the air. The screws do not rust, as long as this protective film is damaged, that is the time for the stainless steel screws to rust. Therefore, stainless steel screws are not that they will not rust, but that they are not easy to rust.
