1. Can withstand larger loads. It has six force-bearing surfaces, which is more resistant to screwing than flat-blade screws and cross-shaped screws with only two surfaces.

2, can be buried in use. That is to say, the whole nut is sunk into the workpiece, which can keep the surface of the workpiece smooth and beautiful.

3. Easy to install. Compared with the outer hexagon screw, the inner hexagon is suitable for more assembly occasions, especially in narrow occasions, so it is very convenient to assemble and maintain, and it is also convenient to debug.

4. Not easy to disassemble. The tools we usually use are adjustable wrenches, screwdrivers and dead wrenches, etc., and special wrenches must be used to remove hexagon socket bolts. Therefore, it is not easy for ordinary people to disassemble. Of course, if you are competitive, you can design all kinds of bizarre structures. The question is whether the special wrench can be manufactured.
