  • Coupling Nut

The common alias of hexagonal long nuts in the fastener industry is hexagon coupling nuts& long nuts&din6334. Unlike regular hexagonal nuts, they have a longer body which allows for increased clamping force and greater surface area contact with the bolt or threaded rod. This makes them ideal for applications where a strong joint is necessary, such as in the construction industry or heavy machinery. Additionally, hexagon coupling nuts are often used in conjunction with threaded rods to create tie rods, which are commonly used in structural bracing applications.

Manufacturing Process

Coupling Nuts are mainly used for connecting non-structural load-bearing bolts such as interior ornaments for railway passenger cars, road passenger cars, and ship berths.

Generally speaking, the standard bolts of M6-M20 size are made by imported Taiwan cold heading machines. 1. Wire pickling - annealing (according to the different fasteners have wire straight shaft) - pickling (wash oxidation skin, etc.) -- drawing line -- forming on the cold heading machine -- tooth rolling machine tooth rolling - heat treatment (6.8 level and nuts below 8 level generally not heat treatment) - electroplating (according to customer needs) - packaging -- shipping.
