The working principle and testing requirements of allen wrenches
source:Industry News release time:2021-04-19 Article author:Rosit Popular:Air band saw
Allen wrenches are also called Allen wrenches. It exerts a force on the screw through torque, which greatly reduces the user's strength and is an indispensable tool in the industrial manufacturing industry. Hexagonal wrench is a commonly used tool for installation and removal. It uses the principle of leverage to turn bolts, screws, nuts and other threads to hold the openings or sets of bolts or nuts.
The working principle of the Allen wrench:
Allen wrenches are usually equipped with a gripping handle at one or both ends of the handle, which can turn the bolt or nut to hold the opening or sleeve of the bolt or nut by applying external force. When in use, an external force is applied to the shank along the direction of thread rotation to turn the bolt or nut.
Testing requirements for allen wrenches:
1. The hardness must meet the specified standards, and the card position must be accurate.
2. There must be no rust, burrs, cracks, spots, etc.
3. The flip-flops are symmetrical, and the laser lettering should be clear.
4. The operation of the turbine of the adjustable hexagon wrench should be flexible, and the pin cannot be loosened.
Hexagonal wrench is used to exert force on the screw through torque, which greatly reduces the user's strength. The shape is L-shaped. It is a special tool for a hexagon socket head screw and is indispensable in industrial manufacturing. Powerful tool.
The socket of the hexagon socket wrench is in the shape of a hexagonal rod, which is simple and lightweight. It is specially used for turning hexagon socket screws.
The allen wrench can be passed down to this day and become an indispensable tool in the industrial manufacturing industry. The key lies in its uniqueness and many advantages:
1. It is simple and lightweight.
2. There are six contact surfaces between the hexagon socket screw and the wrench, which are fully stressed and not easy to damage.
3. It can be used to screw the screws in deep holes.
4. The diameter and length of the wrench determine its torsion force.
5. It can be used to screw very small screws.
6. Easy to manufacture and low cost.
7. Both ends of the wrench can be used.
Its specifications are generally: 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 14, 17, 19, 22, 27
