Example To Solve The Problem Of Loose Thread When Changing Oil Bolts

In order to let everyone have a better understanding of fastener slip teeth, or find a good solution, here Xinchi Fastener Company lists examples to analyze. For example, it is very common to change the oil, but there is also a corresponding wear of the oil drain bolt and the screw hole during the oil change. Once the maintenance technician tightens too much, it will lead to the slip of the oil pan drain screw hole, resulting in a series of costly maintenance projects such as replacing the oil pan.

As a professional fastener company, we are happy to tell you how to perfectly solve the problem of screw hole slip without replacing the oil pan according to our understanding of the fastener industry over the years.

Aluminum oil pan is the mainstream design of the current engine, but the low thread strength is also determined by its material. Therefore, the tightening torque of the oil drain bolt is very high.

The main causes of slippage of oil pan drain bolt

The advantage of aluminum oil pan is light, so the vast majority of the engine oil pan is made of aluminum material, but the bolts are only iron material, so the requirements for tightening strength after the two are matched are extremely high. We all know that the thread strength of the iron bolt is greater, and the slightest mistake may lead to the slip of the oil drain screw thread, so the twisting strength is the key to determining the quality of the oil drain screw thread.

After the iron bolt is connected with the aluminum oil pan, if the tightening torque is too large, it will cause the oil drain screw thread to slip, so many people will choose to replace the oil pan.

Several common problems that cause the bolt to slip

1. The tightening force is too large, resulting in screw hole thread deformation, resulting in slippage.
2. The bolt is skewed when screwed in, resulting in mechanical damage to the aluminum thread.
3. Using a pneumatic wrench, too fast disassembly will damage the thread.
