Gr5 Lug Bolts

Due to its excellent physical and mechanical properties, titanium has been used in racing cars and limited-production sports cars. The application of titanium alloy in the automobile industry can greatly reduce the weight of the automobile, reduce its fuel consumption, protect the environment and reduce noise. The characteristics of titanium have also been well represented in racing cars. Almost all metal parts on the car can be made of titanium and GR5 titanium alloy, such as Gr5 lug bolts, Custom titanium nut, fastening screws GR2, Titanium alloy GR5 hexagon socket screw, thread double-headed screw bolt, G12 Compression nut, Special shape Nut, Titanium Hub Nut, Titanium flat washer, Titanium spring washer, titanium bolt, titanium connecting rod, titanium alloy rocker, titanium alloy buffer rear bracket, titanium alloy exhaust pipe, titanium alloy return pipe, titanium valve, titanium valve Spring brakes, titanium transmission parts, etc. In addition, titanium can also be used for surface coating, and has been used to improve the performance of the surface of the brake plate, which can ensure that the brake plate is light and has a long life. Titanium is used in automobiles to extend the service life of valves, springs and connecting rods.

Hardness of metal materials

     Hardness refers to the ability of a metal material to resist local deformation, especially plastic deformation, indentation or scratches. It is a measure of the hardness of metal materials. The hardness can be divided into the following three types according to different test methods:

     Scratch hardness: mainly used to compare the hardness of different minerals. The method is to choose a rod with a hard end and a soft end, with long scratches on hard objects and short scratches on soft objects.

     Indentation hardness: mainly used for metal materials. The method is to press the specified indenter into the material under test with a certain load, and compare the hardness of the material under test with the size of the local plastic deformation on the surface of the material. Due to the difference in indenter, load and load duration, there are many indentation hardness, mainly Brinell hardness, Rockwell hardness, Vickers hardness and micro hardness.

     Rebound hardness: mainly used for metal materials. The method is to make a special hammer fall freely from a certain height to impact the sample of the material to be tested. How much strain energy is stored (and then released) by the sample during the impact (by the return of the hammer) Jump height measurement) to determine the hardness of the material.

How to deal with common problems of fasteners

Fasteners include: bolts, screws, screws, self-locking nuts, washers, pins. Locking or seizure often occurs on stainless steel, aluminum alloy and titanium alloy fasteners. These metal alloys have anti-corrosion properties and will When the surface is damaged, a thin oxide layer is formed on the metal surface to prevent further corrosion. When the stainless steel is extremely locked, the pressure and heat generated by the tooth pattern will destroy this oxide layer, causing a plug or shear between the metal threads, and then adhesion. When this phenomenon continues to occur, the stainless steel fasteners will be completely locked, and can no longer be removed or continued to be locked. Usually this series of male plug shearing, sticking and locking will occur in just a few seconds. Therefore, the correct understanding of the use of such fasteners can prevent this phenomenon.

1. Select the product correctly: Before use, confirm whether the mechanical properties of the product can meet the requirements of use, such as the tensile strength of titanium alloy screws and the guaranteed load of titanium alloy nuts. The length of the screw should be selected appropriately, which shall be subject to 1-2 pitches of the nut after being tightened.

2. Check whether the thread is rough before use, and whether there is iron filings or dirt on the thread. These things often cause lockup.

3. The GR5 titanium alloy fasteners can be lubricated before use:

It is recommended to use butter, aluminum sulfide, mica, graphite or talc for lubrication. Recently, it is common to use the wax dipping place to do lubrication and anti-locking

4. Pay attention to the method of use when using:

       a. The speed and power that can enter should be appropriate, not too fast or too large. Try to use pull wrenches or socket wrenches as much as possible, and avoid using movable wrenches or electric wrenches. Because the speed is too fast, the temperature will rise rapidly and cause lockup. .

       b. In the direction of force, the GR5 titanium alloy nut must be screwed in perpendicular to the axis of the GR5 titanium alloy screw.

5. The use of a hot ring can effectively prevent the problem of over-locking.
