A Brief Introduction To Several Commonly Used Explosion-proof Wrenches

Explosion proof wrench is a commonly used tool for disassembling and installing threaded joints (bolts and nuts), and is also one of the industrial products purchased in large quantities by various industrial product procurement malls. Due to the different specific structures, positions, and stress intensities of threaded joints, wrenches are also divided into many types. Here is a brief introduction to several commonly used wrenches and the ring wrench used for striking:
1. Strike the plum blossom wrench
The inner holes on both ends of the ring wrench are hexagonal. According to the closure size, it is divided into 8-10mm, 12-14mm, 17-19mm, etc.
When using, the appropriate closing size of the tapping ring wrench should be selected according to the size of the bolt or nut. Compared to open-end wrenches, the ring wrench can be rotated and re inserted into the socket after pulling 30 degrees. Suitable for narrow environments, it is not easy to slip off during use.
2. Dual purpose wrench
One end of the dual-purpose wrench is an open-end wrench, and the other end is a Phillips wrench.
3. Socket wrench
A socket wrench is a convenient, flexible, and stable tool for disassembling bolts. The corners of the nut are not easily damaged during use. The sleeve is in the shape of a short tube, with one end being a twelve or hexagonal shape, which can cover the bolt head; The other end is equipped with a square hole that can be matched with the square tenon supporting the handle. The commonly used socket wrenches include 6.3mm series, 10mm series, and 12.5mm series. In addition to commonly used standard sockets, there are many special sockets such as hexagonal long sockets, hexagonal or twelve pointed flower sockets, pneumatic sockets, screwdriver sockets, etc.
4. Activity wrench
The adjustable wrench, also known as the adjustable wrench, can adjust the opening size within a certain range and is suitable for irregular bolts or nuts. Its specifications are expressed as the width of the large opening x the length of the wrench (mm).
When in use, the jaws should be adjusted to the same width as the opposite edge of the bolt or nut and tightened so that the wrench can move the jaws and withstand the thrust, and fix the jaws to withstand the tension.
The disadvantage of adjustable wrenches is that they are not easy to operate, requiring the rotation of the worm to open or narrow the adjustable jaws, and the wrench is prone to slipping off the bolt.
5. Solid wrench
Solid wrench, also known as open-end wrench, is mainly used for tightening and disassembling nuts and bolts of universal standard specifications. The opening direction of a solid wrench is offset from the handle by an angle, usually 15 degrees, 45 degrees, 90 degrees, etc., to facilitate pulling in restricted areas. Its specifications are represented by the width of the openings at both ends (mm). Solid wrenches are usually forged from 45 steel and 50 steel and undergo heat treatment. Some foreign solid wrenches use imperial units and are suitable for disassembling imperial bolts.
When using, a solid wrench with the corresponding opening size should be selected according to the size of the bolt or nut. To prevent damage or slippage of the wrench, the pulling force should be applied to the side with a thicker opening.
6. Torque wrench
Torque wrenches are mainly used for assembling bolts and nuts with specified torque values. For example, bolts for cylinder head, connecting rod, crankshaft main bearing, etc. The commonly used torque wrenches include preload type and pointer type.
7. Electric wrench
Electric wrench is a type of wrench powered by a power source or battery, suitable for installing bolts on steel structures. It is mainly divided into impact wrenches, torque wrenches, fixed torque wrenches, angle wrenches, hydraulic wrenches, etc.
