First of all, the hexagon socket set screws are divided into different shapes according to their shapes: the top of the cylindrical end set screw is a cylinder, and the top of the hexagonal socket set screw is a cone, and the application of various shapes of screws is also different: 1. Hexagonal ones are called screws, and external hexagonal ones are called bolts. In use, hexagon socket screws are mostly used to screw into the internal thread of the part, and bolts are mostly used for external links, mostly connected with external hexagon nuts. 2. The hexagon socket screw is beautiful, and the nut has no direction, unlike the outer hexagon bolt. For example, there are multiple bolt heads exposed on the table. If the direction of his head is not unified, it will feel messy, and the hexagon socket will give People feel neat. 3. In addition, in use, most of the hexagon socket screws are used in places where the force is not too large, such as electronic and mechanical equipment. Large-scale equipment with greater stress, such as heavy machinery, metallurgical equipment, and large-scale pressure machinery, use less hexagon socket screws. Of course, the use is not absolute. I have also seen some applications in coal excavators and large construction machinery, but they are relatively few. 4. Hexagon socket bolts are divided into cylindrical head socket head bolts according to the head. This is the most commonly used, and there are many types of it. According to the material, there are iron ones, that is, carbon steel and stainless steel. Stainless steel hexagon socket bolts are also made of stainless steel SUS304 and SUS202. 5. Hexagon socket head bolts with semi-circle head, which are also called pan head socket head cap bolts. Countersunk head hexagon socket head bolts, the head is flat, and the inside is hexagon socket. There is also a special kind of national standard called headless hexagon socket bolt. Also known as machine screw, payment screw, set screw. These are all common names for headless socket head cap bolts, but they all mean the same thing. Of course, there are also some flower-shaped socket head socket head bolts. This application is relatively rare, and it is basically difficult to see in the market.
Hexagon socket end set screw, hexagon flat end set screw, hexagon cylindrical end set screw. 1. Discuss with the manufacturer and the customer, and use high-quality hexagon tip set screws to produce wire. On the other hand, manufacturers must remember that the production of good quality inner hexagon tip set screws to harden processing, and must require hardening factory to achieve the specified hardness indicators.
