The socket head of the hexagon screw is round outside, the middle is concave hexagon.This structure has obvious advantages.The socket head of the hexagon screw is round outside, the middle is concave hexagon.This structure has obvious advantages.
1. More load.It has six stress surface, compared to only two surface of the word screw and cross screw more to hold the screw.
Note: the inner hexagon bolt material is generally made of stainless steel, carbon steel, alloy steel, and other types of screw material basically no difference, the higher the performance of the higher the strength, the choice of screws, must be strictly according to the use of the requirements of the choice of suitable performance level of screws, grades are different, the price is not the same.
2. You can bury your head in the sand.That is, the whole nut is sunk into the workpiece internal, can maintain the surface of the workpiece flat, beautiful.
3. Easy installation.Relative to the hexagon screw, hexagon is suitable for more assembly occasions, especially narrow occasions, so it is very convenient for assembly and maintenance, debugging is also convenient.
4, not easy to remove.We commonly used tools have adjustable wrench, screwdriver and wrench, and remove hexagon bolt must use a special wrench, so, the general people are not easy to remove, this is also a benefit.
As we all know, the outer hexagon screw is exposed to the outside, the wrench has to have a certain space to screw it, the need for a large hole or out.And inside hexagonal need very small countersunk hole, do not consider a space when, inside hexagonal basically is chicken rib.
Therefore, what kind of screw application, or depending on the use of occasion.
