¿Por qué los ingenieros están tan interesados ​​en usar el perno de zócalo hexadecimal?

We all know that the screw head of the hex socket bolt is round on the outside and concave in the middle. This structure actually has obvious advantages.

1. The hex socket bolt can withstand greater loads. It has six force-bearing surfaces, which is more resistant to twisting than the slotted screws and cross screws with only two surfaces.

2. The hex socket bolt can be countersunk during use, that is, the entire nut is sunk into the inside of the workpiece, which can keep the surface of the workpiece flat and beautiful.

3. Compared with the external hexagonal screw, the hexagon socket is suitable for more assembly occasions, especially narrow occasions, so it is very convenient to assemble and repair, and it is also convenient to debug.

4. The tools we usually use are wrenches, screwdrivers, and fixed wrenches, etc., and special wrenches must be used to disassemble the hex socket bolts, so it is not easy for ordinary people to disassemble, which is also a benefit.
