Production description
The outer hexagon screw is a matching nut used to fasten and connect two connected parts with through holes and components. Hex head screws are commonly used bolts. It is more important to use Class A and Class B outer hexagon. In addition, it is often used in the occasion of high assembly accuracy, large impact, vibration or cross rate load. Grade C outer 66 screws are used in situations where the surface is rough and the assembly accuracy is not required.
GB series, Q standard series, DIN German standard series, IFI American standard series, BS British standard series, JIS Japanese standard series, ISO international standard series, etc.
Hexagonal nut and screws, bolts, screws with the use of each other, from the role of connecting and fastening parts. The type 1 six-purpose nut is the most widely used, and the class C nut is used on the machine, equipment or structure with rough surface and low precision requirement Class A and class B nuts are used for machines, equipment or structures with smooth surfaces and high requirements for accuracy. Type 2 hex nut thickness m is thicker, often used for the occasion of Assembly and disassembly. The thickness m of hexagon thin nut is thinner, which is used in the situation that the surface space of the connecting parts is limited.
One of the standards for hexagon bolts is the level standard, which is divided into 4.8 and 8.
