What Are Hexagon Socket Screws?

The hexagon socket head screwdriver looks like a "7". Cut the two ends of the hexagonal steel bar and bend it to 90 degrees to become a hexagon socket head screw wrench. It is sold in hardware tool stores. The hexagon socket screws are divided by head. Cylindrical head hexagon socket bolts, and there are many varieties of it itself, according to the raw materials are divided into iron, that is, carbon steel and stainless steel. Stainless steel hexagon socket bolts also have stainless steel SUS304 and SUS202 and other raw materials, semi-circle head hexagon socket head bolts, which are also called pan head hexagon socket head bolts. Countersunk head hexagon socket head bolts, the head is flat, and the inside is hexagon socket; there is also a variety of national standards that are more special, called headless hexagon socket head bolts, which are often called machine screws, payment screws, set screws . These are all common names for headless hexagon socket head bolts, but the meaning is the same. Of course, there are also some flower-shaped hexagon socket head socket head bolts, which are rarely used and are basically difficult to see in the market.

Hexagon socket head screws are often used in machinery. They have the characteristics of tightening, disassembling, and not easy to slip. The socket head wrench is generally a 90° bend. The curved end is long and the side is short. Holding the long side saves a lot of effort and tightens the screws better. The long end has a round head (hexagonal cylinder is similar to a sphere) and a flat head. The round head can be easily inserted into the screw hole and disassembled quickly. The production cost of the outer hexagon is much lower than that of the inner hexagon. It also has a screw head (the force bearing position of the wrench) that is thinner than the inner hexagon, and some places cannot be replaced by the inner hexagon. In addition, machines with low cost, low power strength and low precision requirements use less hexagon socket screws than external hexagon screws.
