1.Product Introduction
These threaded rods, also called class 12.9 steel threaded rods black oxide , are relatively long rods that are fully threaded along the complete length of the rod.Hot dip galvanizing is a thick zinc coating offering more corrosion protection. Preferable for applications where exposed to the elements. Use with over-tapped galvanized nuts.
These steel class 12.9 steel threaded rods black oxide offer a combination of high strength and fracture resistance, and are often used in the rail and motor industries, and the manufacture of process equipment.
Typically applied as self-colour, zinc plated threaded rod is also available for lengths up to 1 metre.
