product description:

Cylinder-head hexagon socket screws, also referred to as hexagon socket bolts, cup-head screws, and hexagon socket screws have different names, but they represent the same meaning.Commonly used hexagon socket head screws also have 4.8, 8.8, 10.9, and 12.9.Also called hexagon socket screws, also called hexagon socket bolts.

Hexagon socket screws are often used in machinery, mainly for easy fastening, disassembly, and not easy to slip corners. Allen wrenches are generally a 90° turn, and the bent end is long and the other is short. When the short side is used to drive the screw, Holding the long side can save a lot of force and better tighten the screws. The long end has a round head (a hexagonal cylinder is similar to a sphere) and a flat head. The round head can be easily inserted into the screw hole for easy removal. The manufacturing cost of the outer hexagon is much lower than that of the inner hexagon. Its advantage is that the screw head (the force position of the wrench) is thinner than the inner hexagon, and some places cannot be replaced by the inner hexagon. In addition, the cost is low, the power strength is small, and the accuracy is small. Low-demand machines use less hexagonal socket screws than external hexagonal screws.
