What are the specifications of the socket wrench?
Generally speaking, the specifications of socket wrenches are different at home and abroad, resulting in different product specifications. In our country, the socket wrench is calculated according to the domestic unit of calculation, which is called the metric system. It is based on the British unit of calculation known as the imperial system.
Due to some missing mantissas in the conversion between metric system and imperial system, there are some differences in product specifications and sizes, but generally speaking, they are still common. Depending on the conversion unit at home and abroad, the machines manufactured are also different, so the required socket wrenches are also different.
But in general, socket wrenches are used in auto repairs and machine repairs. Therefore, except for some newly introduced foreign equipment, it can be used only by purchasing metric products at home. How to calculate 1 inch = 2.54cm in general calculation, but some manufacturers directly convert it into 1 inch = 2.5cm, so the products in the industry are not very accurate, but for large manufacturers, they are calculated according to the former one of. This is also the most basic national standard. According to the standard, the socket of the socket wrench is generally controlled centrally and has two sides;
One side: Square mouth (according to the connection method of the socket and the wrench)
One side: 6 corners, 8 corners, 12 corners (according to the shape and size of machine and automobile nuts)
Square mouth: used for the link between the sleeve and the helper, these are the four sides, the length of the opposite side is the side length, the general Huafeng giant arrow tool is the same as other manufacturers, generally only English: 1/4, 3/8 , 1/2, 3/4 four specifications; according to the metric system: 6.3mm, 10mm, 12.5mm, 19mm; in fact, there is such a formula in the industry: 1/4=6.3mm, 3/8=10mm explanation, 1 /2=12.5mm, 3/4=19mm is a general formula in the hand tool industry.
For example, this 1/2" means that the side opposite the wrench linkage is 12.5mm long.
The other side is 6 corners, 8 corners, and 12 corners, depending on the needs of the car and machine nuts.
