Hexagon socket head cap screws are also referred to as hexagon socket head cap screws, which are similar to countersunk head screws. The common ones are imperial and metric, and the most common used materials are stainless steel and carbon steel.
Countersunk head hexagon socket bolts are often used on mechanical equipment, and their advantages lie in fastening, disassembly, and not easy to slip angle. The matching Allen wrench is usually L-shaped. One side is longer and the other is shorter. The short end is used for tightening the bolts, while the long end is mainly for the convenience of hand force.
Many people have questions, why should it be designed as a hexagon instead of a square, pentagon or other shapes?
1. Turn the hexagonal screw 60° to restore the graphics. If the space is relatively narrow, the screw can be installed as long as the wrench can be turned 60 degrees. This is the product of a compromise between the twisting angle and the side length.
2. If it is a square, the side length is long enough, but it needs to be twisted 90 degrees to restore the graphics, which is not suitable for installation in a small space; if it is an octagon or a decagon, the angle of the graphics restoration is small, but the side length of the force It is also small and easy to round.
3. If it is a screw with an odd number of sides, the two sides of the wrench are not parallel. There were only fork-shaped wrenches in the early days, and the head of the wrench with an odd number of sides has a horn-shaped opening, which seems not suitable for exerting force.
Advantages of using hexagon socket bolts
1. Can withstand greater load.
It has six force-bearing surfaces, which are wider and more uniform than flat-head screws and cross-shaped screws with only two surfaces.
2. It can be made into a countersunk head.
That is to say, the whole nut sinks into the inside of the work piece, which can keep the surface of the work piece smooth and beautiful.
3. Easy to install.
Compared with the outer hexagonal screw, the inner hexagon is suitable for more assembly occasions, especially narrow occasions, so it is very convenient for assembly and maintenance, and it is also convenient for debugging.
4. Not easy to disassemble.
The tools we usually use are adjustable wrench, screwdriver and dull wrench, etc., but a special wrench must be used to disassemble the hexagon socket head bolt. Therefore, it is not easy for ordinary people to disassemble. Of course, if you have other ideas, we are happy to cooperate with your design.
