More Complete Info of the Bolts (Recommended)
February 14,2022
The application of fasteners is self-evident, from small instruments to large machinery, there are many kinds, you can find a specific variety according to your needs. It makes things stronger.
The variety of fasteners is also very rich, but today's main topic is about The Bolts, and I will discuss it more intensively. Let's start with what are the bolts.
What is a bolt?
A bolt is usually used in conjunction with a nut, which is a fastener composed of a head and a screw with external threads. Its main function is to allow two parts with through holes to be tightly connected.
It should be noted that bolts generally refer to screws with larger diameters, which may not have heads, such as stud bolts.
Difference between nuts and bolts
They are used together and are obviously different and different parts. But there are still people who have doubts about it. The nut is a sleeve with a hole, and the inner wall of the hole has a certain thread, in order to better fit the threaded cylinder of the bolt.
What is a single end stud bolt?
Both Single End Stud Bolt and single end studs have no head, but only one end is threaded.
What is a double end stud?
Threaded at both ends, with a polished rod (unthreaded) in the middle, typically used in plumbing, industry, etc.
The difference between single head bolts, stud bolts, and stud bolts
There are three main differences between them:
- The bolt length of single-headed bolts is less than that of double-headed bolts.
- Stud bolts are more widely used. For example, if the roof beam is suspended from a monorail, stud bolts must be used.
- Single-headed studs are used in general places, while double-headed studs are mainly used in places with high temperature, high pressure and large temperature changes.
Maintenance tips
Small fasteners like bolts, while inconspicuous, keep large equipment tight. However, over time, coupled with daily use, external loads can be affected by vibration and air temperature to reduce the friction between the nut and the bolt, resulting in slack. So we need to pay attention to their maintenance and maintenance. Here we take the maintenance of stud bolts as an example.
Replace the engine bush shaft in time
Long-term mechanical friction can cause problems with the studs, at which point you need to remove the engine oil pan and check its condition. If the gap between the bearing shells is too large, it needs to be replaced in time.
Replace the stud and connecting rod bolts
If you need to replace the studs, then the connecting rod bolts also need to be replaced.
Check them in time
Especially when some large equipment makes abnormal noises and some instability, please check it in time.
Check new accessories
Sometimes repairs require the replacement of new parts, you have to check the head and guide part of the new studs (important). Plus, whether there are cracks and dents in the thread, whether the thread pitch is abnormal, etc.
Note: When replacing, you need to pay attention to the proper torque and select the matching nuts and bolts.
