Machine Screws
Hexagon socket head cap screws (Material: steel)(Full teeth)

Characteristics of socket head cap screws
1. It is not easy to slip teeth.
2. It can be countersunk in use, that is, the whole nut is sunk into the workpiece, which can keep the surface of the workpiece smooth and beautiful.
3. More assembly occasions, especially narrow occasions, so it is very convenient to assemble and maintain, and it is also convenient to debug.
4. The tools we usually use are adjustable wrenches, screwdrivers and open-end wrenches, etc., and special wrenches must be used to remove the socket head cap screws. Therefore, it is not easy for ordinary people to disassemble, which is also a benefit.

In addition to saving space for fixing parts, low-head screws can also be used as cover bolts. They are mainly used in automobiles, construction, machinery, home appliances, electronic industries, locomotives and bicycle parts.
