1. The outer edge of the screw head of the hexagon socket screw is round, and the middle is a concave hexagon. Such a structure bears a greater load. It has six force-bearing surfaces, which are more durable than flat-blade screws and cross-shaped screws with only two surfaces.
Note: The material of hexagonal socket head bolts is generally made of stainless steel, carbon steel, and alloy steel. There is basically no difference in material from other types of screws. The higher the performance level, the greater the strength. When selecting screws, you must choose strictly according to the use requirements. Screws with suitable performance grades have different prices.
2. You can deal with it with your head down. That is to say, the whole nut sinks into the inside of the workpiece, which can keep the surface of the workpiece 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 wrenches, screwdrivers and dull wrenches, etc., but special wrenches must be used to disassemble the hexagon socket head bolts. Therefore, it is not easy for ordinary people to disassemble, which is also a benefit.
