What Are Socket Bits?
Socket bits are tools used with power drills and impact drivers.
A set of socket bits of different shapes and sizes is provided for each power tool.
It is connected to the end of the rotating shaft of a power tool so that it can be covered.
Uses of Socket Bits
Socket bits are used in power tools such as power drills and impact drivers, as well as socket wrenches and manual screwdrivers.
Tools using socket bits has very wide range of applications, from DIY projects for the general public to small-scale store renovations to construction work on large commercial buildings.
Principle of Socket Bits
Socket bits are joined to the main body of the tool by inserting them so that they cover the shape of the hole in the rotating shaft of the tool body. There are various types of insert shapes, but most are hexagonal in shape.
In addition, there are several sizes of hexagonal shapes. For electric and air screwdrivers, three main types are used: 5 mm, 6.35 mm, and 8 mm on the opposite sides. For small electric screwdrivers, 4 or 5 mm diagonals are used.
Other Information on Socket Bits
1. Standards of Socket Bits
There are two main types of socket bits: A-type and B-type. Each has a specific length from the groove on the bit to the tip. Specifically, the tip of the A-type is 13 mm, and the tip of the B-type is 9 mm or 9.5 mm. Most electric screwdrivers made by domestic manufacturers use the B type.
2. Heat Treatment Hardness of Socket Bits
There are five levels of heat treatment classification for the hardness of socket bits.
- S and E
S and E are the lowest hardness socket bits and are used for high impact tools. - G
G is the standard hardness and is used for tapping screws and small screws. - H
H is a high hardness and is used for wood screws and self-drilling screws. - X
X is the highest hardness and is used for precision small screws and automatic machine mounting.
3. Types of Hexagonal Socket Bits
Among socket bits, those used for fastening hexagonal bolts are called hexagon socket bits.
Shaft press-fit type
The hexagonal socket part and the shaft part are separate structure of the hexagonal socket bits. They are mainly used for building equipment applications.
Integral Molded Bits
One-piece molded bits have a hexagonal socket bits and shaft in a single structure of one piece. They are mainly used for small-diameter bolts and torque-controlled fastening operations. The one-piece design provides high rigidity, but stress is concentrated on the part where the thickness of the shaft changes during tightening work. For this reason, they are more prone to breakage than other types of hexagon socket bits.
Bit interchangeable type
In the interchangeable bit type, the hexagonal shaft portion of the hexagonal socket bits are interchangeable. Since the hexagonal shaft part, which is prone to breakage, can be replaced, the bit can be used for a long time. However, it is larger and heavier than other types of hexagon socket bits due to the replacement structure.
Socket adapters
This is a conversion adapter to use a hexagonal socket bits of a square-shaped impact wrench or socket wrench with a hexagonal hole shape, such as an impact driver. Since there are many joints and there is more backlash, it is safer to use it only temporarily.
