Introduction to Heavy Allen Wrench
2011-12-12 12:15:59
The heavy hexagonal wrench is a special tool with L-shaped shape and used for a hexagon socket screw. It is in the shape of hexagonal bar. The heavy hexagonal wrench is specially used for turning the hexagon socket screw. The model of the special tool is based on the size of the hexagonal opposite side, and the size of the bolt is standard.
Q
Safety operation procedures for Allen wrenches
2011-12-12 12:15:59
Safety operation regulations for hexagon socket wrenches 1. Purpose: tighten or disassemble hexagon socket head cap screws and set screws. It is mainly used for assembly and maintenance of machinery manufacturing, automobile, engine, agricultural machinery and other industries. 2. Rules for safe use: ① Do not use the metric Allen wrench for the metric screw, and do not use the metric Allen wrench for the metric screw, so as to avoid slipping and hurting the user. ② It is not allowed to add a sleeve extension arm at the end of the Allen wrench to prevent damage to the Allen wrench. ③ Do not use a steel hammer to hit the Allen wrench, which is easily damaged under impact load. 3. Management and maintenance: ① Carefully check the product certificate and instructions before use. ② Always keep the appearance clean, especially without oil stain. ③ After use, it shall be timely stored and put into the designated tool kit or box, and shall not be stored together with sharp tools. ④ The safety, health and environmental protection representative shall focus on inspection during the monthly inspection. ⑤ The unqualified or damaged parts shall be replaced in time and shall not be repaired by themselves
Q
How to use the Allen key?
2011-12-12 12:15:59
Allen wrench is also called Allen wrench. Common English names include "Allen key (or Allen wrench)" and "Hex key" (or Hex wrench). The "wrench" in the name indicates the "twist" action, which reflects the most important difference between the hexagonal wrench and other common tools (such as the slotted screwdriver and the cross screwdriver). It exerts the force on the screw through the torque, greatly reducing the user's strength. It can be said that among the installation tools involved in the modern furniture industry, the Allen wrench is not the most commonly used, but it is the best.

Q
About the choice of Allen wrench!
2011-12-12 12:15:59
Anything existing must be reasonable! There are different kinds of Allen wrenches for different reasons. As long as you find the best one for yourself.
Regardless of your brain, hands and bottle opener, there should be no more important tool in a bicycle workshop than an Allen wrench. So why do we (the original author) recommend using special tools for bicycles instead of using L-type Allen wrenches or even worse multi-function tools?
In a workshop with perfect tools or in the technician's toolbox of a professional team, you can't decide which wrench is better. Because it depends on everyone's use style and habits. But the key is that you can always find one or two torque wrenches.
Most Allen wrenches can tighten screws, but what you need on a bicycle is higher efficiency, saving time, and increasing your time on the bike.
Of course, the choice of different types of hexagon is not worth mentioning. This is the same as the cushion you stepped on. It varies from person to person. But how to reduce the loading time and abnormal noise is very necessary!
Next, we will introduce different types of wrenches slowly. If you plan to DIY or repair at home, and have no idea about these tools, please read on. (It is also suitable for box wrenches. This kind of screw is also common on high-end bicycles.)
Q
Use of Allen key
2011-12-12 12:15:59
The hexagonal wrench can be handed down today and become an indispensable tool in the industrial manufacturing industry. The key lies in its unique features 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 easily damaged.
3. It can be used to tighten screws in deep holes.
4. The diameter and length of the wrench determine its torsion force.
5. It can be used to tighten very small screws.
6. Easy to manufacture and low cost.
7. Both ends of the wrench can be used.
Q
Which material is the best for Allen wrench
2011-12-12 12:15:59
The best material of Allen wrench 100 is s2, followed by 8660. Carbon steel and chrome-vanadium steel are the conventional ones on the market. Chromium-vanadium steel is better than carbon steel in hardness, wear resistance and corrosion resistance, so it is recommended to choose chrome-vanadium steel. Allen wrench is also called Allen wrench. Common English names include "Allen key (or Allen wrench)" and "Hex key" (or Hex wrench). The "wrench" in the name indicates the "twist" action, which reflects the most important difference between the Allen wrench and other common tools (such as the slotted screwdriver and the cross screwdriver). It exerts the force on the screw through the torque, greatly reducing the user's force intensity. It can be said that among the installation tools involved in the modern furniture industry, the Allen wrench is not the most commonly used, but it is the best one.
Q
What are the sizes, specifications and models of Allen wrenches?
2011-12-12 12:15:59
According to the requirements of national production standards, the shape of general Allen wrench has four parameters. As shown in the figure below, they are the opposite side distance s of the section, the diagonal distance e of the section, the length l of the short side, and the length L of the long side.
The specification, model and size of the Allen wrench are determined by the distance S between the opposite sides of the section. For example, for a 2mm Allen wrench, the distance S between the opposite sides of the wrench section is required to be 1.96-2mm, and for a 4mm Allen wrench, the distance S is required to be 3.95-4mm. Because the hexagon socket wrench is used to screw down the concave screw, the size of the hexagon socket is actually determined by the size of the hexagon hole. If it is large, it must not be plugged in. If it is small, it will not be easy to screw down. It is easy to slip.
The hexagon socket wrench can be divided into metric system and English system. There is little difference in use, but the measurement unit is different. Generally, the hexagon socket metric system has the following specifications and models: 2, 2.5, 3, 4, 5, 6, 7, 8, 10, 12, 14, 17, 19, 22, 24, 27, 32, 36.
Q
Advantages of hexagon socket bolts
2011-12-12 12:15:59
1. Capable of withstanding larger loads. It has six stress surfaces, which are more bearable than flat head screws and cross head screws with only two surfaces.
2. It can be buried in use. That is, the whole nut is sunk into the inside of the workpiece, which can keep the flatness and beauty of the workpiece surface.
3. Easy installation. Compared with the outer hexagon screw, the inner hexagon is suitable for more assembly occasions, especially narrow occasions, so it is very convenient for assembly and maintenance, and also convenient for debugging.
4. It is not easy to disassemble. The tools we usually use include open end wrenches, screwdrivers and solid wrenches, while the special wrenches must be used to remove the hexagon socket bolts. Therefore, it is not easy for ordinary people to disassemble. Of course, if you are competitive, you can design various strange structures. The question is whether the special wrench is easy to manufacture.
Q
Why do many places like to use socket head screws? What's the good of it?
2011-12-12 12:15:59
Many people have questions again. Why should we design a hexagon instead of a four-corner, five-corner or other shape? The hexagonal screw can be restored by turning 60 °. If the space is relatively small, the screws can be installed as long as the wrench can turn 60 degrees, which is the result of compromise between the turning angle and the side length.
If it is a square, the side length is long enough, but it needs to be screwed 90 degrees to restore the graphics, which is not suitable for small space installation; If it is an octagon or a decagon, the angle of graphic reduction is small, but the length of the side under force is also small, and it is easy to round.
If it is a screw with odd side length, then the two sides of the wrench are not parallel. In the early days, there were only fork-shaped wrenches. The wrench head with odd side length is a flare-shaped opening, which seems not suitable for power.
