　　Handan self-tapping nail according to the different head can be divided into which several categories?

　　According to the different head can be divided into: round head, flat head (that is, countersunk head), top pillar head, dome wide edge head, big round head (that is, big flat head), hexagonal bore head, hexagonal bore head, and hexagonal head. Round head: Used to be the head shape. Flat head: a new design that can replace round head and mushroom head. The head is low and has a large diameter, and the circumference of the head is connected along the characteristic of the high shape edge, so that it can play a driving role in the high strength torque, and the head shape is slightly different from that of the cave head.

　　Top pillar head: The diameter of the standard flat top pillar head is smaller than that of the round head, but it is higher because of the depth of the groove. The smaller diameter increases the pressure on the small area and can be tightly combined on the flange and the increased surface. They can be successfully applied to holes in the inner borehole because of the heads in the borehole moulds arranged to ensure centrality. Dome head with wide edge: It is widely used in electrical appliances and tape-recorder because of the internal-cut binding under the head and reduces the wear on the wire components. It provides a more attractive design type for the mid - head type with its full bearing surface. Big round head: Also known as oval head with wide edge, it is a low type, cleverly designed large diameter head. When combined tolerances of additional action permit, it can be used to cover sheet metal holes with larger diameters. A flat cut may also be suggested instead.

　　Hexagonal bore head: a knot with a wrench head height and a hexagonal head size. The hexagonal shape is completely formed by the reverse hole mold, and there is an obvious depression at the top of the head. Hexagonal socket head: such as the standard hexagonal socket head type, but at the same time there is a washer surface in the base of the head to protect the assembly, so as to avoid wrench damage. Sometimes things are more important than what they look like. Hexagon head: This is a standard type of torque applied to the hexagon head, with the feature of trimming sharp sharp angles to close tolerance. It can be recommended for general commercial use, as well as for various standard patterns and thread diameters. Because it needs two processes to make it more expensive than the general hexagonal socket.
