The socket wrench, which can be used in various sizes in combination with the handle, was invented by Snap-on Tools founder Joseph Johnson. Today, it has become an indispensable tool for automobile maintenance.
Socket wrench that can be used for a wide range of purposes and improves work efficiency
“Socket” means “plug in” and socket wrench means “plug-in wrench”.
As the name suggests, the tip is a plug-in type, so you can work with screws of various sizes with a single handle. In addition, there are variations in the types of handles, so you can use them properly according to the place of use and work content.
The socket part is also called “top”, and originally it was only for hexagon head screws, but nowadays, various types of screws such as hexes and Torx are on sale.
A typical handle that combines a socket wrench is a ratchet handle, and a set of a socket and a ratchet handle is also called a box wrench.
In addition to the ratchet, there are T-type and L-type handles, spinner handles and driver handles, and there is also a torque wrench that can manage the tightening torque. It is also very convenient because it can be combined with power tools and air tools.
Socket wrench standard and how to choose
Socket wrenches have a size at the part where the handle and socket are combined, called the “insertion angle”. Since it is a tool originally invented in the United States, the insertion angle is inch standard, and it ranges from 1/4 inch (6.35 mm) to 2-1 / 2 inch (63.5 mm).
Socket wrenches are now available from sources other than Snap-on Tools, but because they are made to this standard, sockets and handles are compatible across manufacturers.
There are three types of insertion angles that are generally used: 1/4 inch (6.35 mm), 3/8 inch (9.5 mm), and 1/3 inch (12.7 mm). The larger the insertion angle, the greater the force that can be handled. increase.
Also, there are differences in the size range of tools that can be used, so make sure that you can use the size of the screw you want before purchasing.
Choose handles that suit your work. However, even if the handle is the same, there are things with different lengths such as long type, so when choosing it, make sure that it suits the purpose and place of use.
