Division of coarse six angle bolts and refined six corner screws in the US system


In the American system, the habit of refining the six angle screw is called "Hex Cap Screws", and the coarse six angle bolt is called "Hex Bolts". The division of rough bolts and refined screws is also distinguished by a gasket and no gasket, generally without a gasket, a six angle bolt, a large type of tolerance, known as a rough six angle bolt, and a six angle screw with a gasket surface, and a smaller tolerance, called a refined six angle screw.
