Fasteners are essential in construction, manufacturing, and various other industries. Super duplex fasteners, in particular, have stood out because of their unique properties, making them ideal for heavy-duty applications. Super duplex stainless steel combines two types of stainless steel – austenitic and ferritic. This alloy contains high levels of chromium, molybdenum, and nitrogen. It is categorized into three main types; super duplex bolts, super duplex screws, and super duplex nuts. Super duplex bolts come in different shapes, sizes, and designs, including hex, carriage, and lag bolts. Super duplex screws are available in varied head types, including flat, pan, round, and hex.

Super Duplex Fasteners are highly resistant to corrosion, pitting, and cracking, making them useful in harsh environments. They are commonly used in oil and gas, desalination, and petrochemical industries, where exposure to seawater, acidic or alkaline solutions, and high temperatures is prevalent. Additionally, they are suitable for marine structures, industrial and agricultural machinery, medical equipment, and transportation infrastructure.
