Socket Screws can be used in most circumstances as the cap head can be either hidden or embossed against the mating material. Socket screws are easy to assemble and disassemble by L-wrench or powered driver bit. L-wrench or driver bit are the tools to suit set screws. These wrenches are an application of lever system, which can save user's energy. Socket Screws are usually heat treated as the hex socket must be hard enough to take torque generated by driver, usually in grade 8.8 to 12.9, heat treated from alloy SCM435 or A2 / A4 in stainless steel.
