Hex Coupling Nuts DIN6334 Hexagon Threaded Connecting nut M4 M5 M6 M16 Long Hex Coupling Nuts

Joint connectors have a wide range of applications in the industrial and electronic fields, mainly divided into the following categories:

Welding joint female head: Welding joint female head, also known as pipe joint, is usually used to connect two sections of metal pipes in a pipeline. Common forms of welding joints include butt welding, fillet welding, T-welding, etc. This type of joint female head has the characteristics of high strength and good sealing, and is widely used in fields such as chemical, petroleum, aviation, shipbuilding, etc.

Threaded joint female head: The threaded joint female head connects two components through threads. Common types of threaded connectors include internal threaded connectors, external threaded connectors, flange threaded connectors, etc. This type of joint has the advantages of simple structure, easy disassembly and assembly, and good sealing, and is widely used in fields such as water conservancy, tap water, and petrochemicals.

Clamp joint female head: The clamp joint female head, also known as a card joint, clamps two pipes with a clamp. Usually composed of snap rings, cards, rubber gaskets, etc. The clamp joint female head has the advantages of easy installation and flexible disassembly, and is widely used in fields such as water supply, drainage, and heating.

Flange joint female head: The flange joint female head connects two components through flange bolts. Common flange joint female heads include flat flange, ductile iron flange, winch flange, etc. The flange joint female head has the advantages of strong pressure bearing capacity, easy maintenance, and suitability for high temperature, high pressure and other working conditions, and is widely used in fields such as petrochemicals, natural gas, and electricity.

These different types of joint female heads are selected according to actual working conditions and requirements, ensuring firm pipeline connections, smooth fluid flow, and no leakage
