Screwdrivers are commonly used tools in our lives. In our home life, we must repair them. At this time, screwdrivers can come in handy. However, there are many screwdrivers on the market. What brand is good and what material is good, so today I will edit Let me tell you what material is good for the multi-function screwdriver.

Why look at the material? First of all, the hardness of the screwdriver is very large, and its hardness is also used when it is used. Therefore, if the selected screwdriver is not suitable, it is easy to cause great damage to the screw under improper use. At the same time, the hardness is too high. Poor, it will also make the wear resistance of the screw worse. Therefore, a good screwdriver is a good screwdriver. When using it, there will be no worries. Therefore, we must use snacks when selecting.

Generally speaking, the bit of a good quality screwdriver is made of spring steel with relatively high hardness. The basic standard is hard but not brittle, and tough but hard. If the screw head opening becomes bald and slippery, you can hit the screwdriver with a hammer at this time to make the screw groove deeper to facilitate the screw removal. At this time, make sure that the screwdriver is undamaged. Screwdrivers are often used to pry things in life, so at this time, screwdrivers are required to have a certain degree of toughness and not bend or bend. Generally speaking, it is hoped that the hardness of the screwdriver head is greater than HRC60, and it is not easy to rust. If it is easy to rust, the best screwdriver will no longer work.

1-Chromium molybdenum steel (Cr-Mo)

This steel has good impact resistance, good hardness and toughness. It is generally used to make top screwdrivers and small hexagonal wrenches. It is an alloy of chromium, molybdenum, iron, and carbon, but the material is more expensive.

2-chrome vanadium steel (Cr-V)

This material has good strength and toughness, and is an ideal material for making wrenches, screwdrivers, etc. It is an alloy of chromium and vanadium. It is not as expensive as it is. It is a general-purpose material for screwdrivers in life.

3-Carbon Steel (CS)

Carbon steel refers to a type of steel that does not add other specific elements and the mass fraction of carbon is less than 2.11%. The advantage is high hardness and high strength, but the disadvantage is poor toughness. This steel is not suitable for use as a screwdriver, but it is widely used in some general tool materials.

4-S2 tool steel

This alloy is an excellent impact-resistant steel, used to make high-hardness Allen wrenches, screwdrivers, etc. Tools made of this steel have a sufficiently high hardness after heat treatment. Possess good wear resistance, certain strength and toughness. But in the actual selection and application of screwdrivers, it is not as good as chrome vanadium steel.

Well, the above is all about the introduction of the good material of the multi-function screwdriver. The common tool in life is the screwdriver. No matter what is broken, we must try to repair it first, so as to ensure that our life is more comfortable and convenient. , If you still have related questions, you are welcome to follow us for a long time.
