Contents

A Coupling Nut is usually used to fasten two threaded ends most commonly a threaded bar/rod or studs.As seen it is a hex bodied fasteners similar to hex nut with length factor.Hex Coupling nuts are long hex nuts beveled from both the sides. They are used to attach two externally threaded objects effectively. E.g. using coupling nuts can join two threaded rods.

We produce Hex coupling Nuts also called as Hex Coupler/Hex Coupling Nuts in Stainless Steel grades, Alloy Steel, Inconel Alloy,Monel, Incoloy, Hastelloy C, Alloy 20, Duplex & Super Duplex, AISI 904L,etc.We manufacture these coupling nuts in various sizes as per DIN 6334 Standard.

Coupling Nuts Useful Information

coupling nut, also known as extension nut, is a threaded fastener for joining two male threads, most commonly athreaded rod, but also pipes. The outside of the fastener is usually a hex so a wrench can hold it. Variations includereducing coupling nuts, for joining two different size threads; sight hole coupling nuts, which have a sight hole for observing the amount of engagement; and coupling nuts with left-handed threads. These are used to make up long rod assemblies from shorter lengths of rods. The rods are threaded into the coupling nut for a certain distance. Coupling nut dimensions are described by the Industrial Fasteners Institute in standard IFI-128. It is given a plain finish. It is either cold drawn or hot rolleddepending on the bar stock used. Coupling nuts threaded with two different thread sizes and profiles are called reducing coupling nuts.
