The mast does not pull out the measuring aperture

In the aperture size processing, there is often a requirement that the extraction of the mast surface must be measured, as shown in Fig. 1. In the case where the mast is not allowed to be withdrawn, it is obvious that the universal inner diameter gauge cannot be measured. The general case is to take the bow micrometer measurement as shown in Figure 2. The bow micrometer is fitted with a differential head at one end and a fixed probe at the other end. When using, it is necessary to find the minimum value in the axial direction and find the maximum value in the radial direction. Obviously, the operation is very inconvenient. I will introduce a new method below, which is simple and convenient. Available at

Carbon Steel Bolts

Mild steel, sometimes referred to as carbon steel or ordinary carbon steel, is defined as having a carbon content of no more than 2% and no other perceptible alloy elements.
This steel is produced on a large scale and is the largest part of the steel production industry. You will be able to find it in various applications, fasteners and fasteners.
Generally, this kind of steel has high strength, high hardness and magnetism, and is usually used in motors and electrical appliances - however, their corrosion resistance is poor, and should not be used in corrosive environment without protective coating or coating.
There are some differences between low-carbon steel and steel, because steel has lower toughness and greater brittleness, and low-carbon steel can be further strengthened by adding carbon.
If you need more information or want to order carbon steel products, such as hexagon Bolts, carriage bolts, flange bolts, U-bolts, union bolts, expansion bolts, threaded rods, please contact us.
