There are standard duplex, lean duplex and super duplex fasteners based on the chemical composition. The Super Duplex Screw is a super duplex made fastener. The size of the fasteners range from 3mm to 200mm with the lengths ranging from M02 to M30. There are different types such as the ASTM A479 UNS S32750 Threaded Rod which is used to connect two components with or without a nut. The specification is the ASTM A479 for this grade of fasteners with standards ranging as ASTM, BS, IS and other international standards. The 2507 Super Duplex Nuts and Bolts have resistance to crevice and pitting corrosion, oxidation and atmospheric corrosion. Therefore the application of the Super Duplex Studs can be seen in the general, petroleum, petrochemical, sea water, marine and in other industrial applications. Regal Sales Corporation is a leading manufacturer and supplier of the different Super Duplex 2507 Bolts and other fasteners. Please feel free to contact us for more information on the different types such as the super duplex washers and other fasteners.
