Fasteners and standard parts, traditional fasteners include: bolts, studs, screws, nuts, washers, pins, rivets, assembly and so on. It is mainly used for the fastening of a type of mechanical parts and has a wide range of applications: mechanical fasteners, construction fasteners, structural fasteners, tools, fasteners, traffic fasteners, and the like. There are many varieties of specifications, so the national standard fasteners. People are also often referred to as standard fasteners.
The use of fasteners is also standard, GB, DIN, ISO, ANSI, BS, JIS. According to the standards of different countries, this makes fasteners like Jiangwei Xin Fasteners Co., Ltd. able to meet the requirements of fasteners produced by various standards organizations.
Universal fasteners have the following types:
1, bolts, nut fastening parts cooperation, two holes, tighten the nuts on the bolts, the two parts can be separated, so the bolt connection is a detachable connection.
2, studs, bolt heads. The thickness of the connecting part, the compactness of the structure, or the fact that it is large or because of frequent relocation, should not be adopted as one of the main actions on the occasion of bolting.
3, screw, machine screws, tapping screws, screws for special purposes. Can be fitted with a nut, but also can not help with the nut. Self-tapping screws are similar to machine screws, but this thread is commonly used for special, commonly used components for two thin metal parts. Wood screws are used exclusively for special screw terminal blocks.
4, the threaded hole in the nut, the shape of the flat hex nut is generally represented, there is also a square nut or flat round nut or shaped nut, bolt, stud or machine screw, used to fasten two parts as a whole.
5, washers, flat round fasteners. The bolts, screws or nuts on the bearing surface and the surface of the connecting part play an increasingly larger contact surface area of the connecting portion, lowering the pressure per unit area, and protecting the other type of elasticity of the connecting member surface from being damaged. Gaskets also prevent nuts from retracting.
6. Rivets, including nail heads and extremely different fasteners, are used to fasten two hole parts (or components) as a whole. This connection is called riveting or riveting. Connect with seal.
7, Needle, mainly used for part positioning, some can also be used for connecting parts, fixing parts, transmitting power, or locking other fasteners.
8, components, such as mechanical screws (, independent screws or bolts), flat washers (or spring washers, lock washers) combination supply.
