High Tensile Joint Nut 40Cr Hex Coupling Nut for Railway Fastening
Connector
Coupling nuts are used in joining threaded rods where span of application
exceeds 144" or where a threaded fitting is used with threaded rod
in suspension applications. ASTM A-563 Grade A. ASME B1.1 UNC Class
2B thread requirement. Zinc plating, retards the corrosion rate in
a normal atmosphere.
Hex Coupling Nuts are defined by their elongated hexagonal shape
and used to connect two pieces of threaded material at opposite
ends. A coupling nut has a sight hole which allows visual
verifications that the threads are fully engaged. Hex coupling nuts
are made to be highly enduring and able to suit the wide variety of
applications they are commonly used for.
1. Right hand thread
2. Coupling nuts are threaded fasteners for joining two male
threads, most commonly threaded rod
3. Coupling nuts are used to make up long rod assemblies from
shorter lengths of rods
4. Stainless steel
