Grade 2 Steel Hex Flange Nut, Zinc Plated Finish, Self-Locking Serrated Flange, ASME B18.2.2, 5/8"-18 Threads, 15/16" Width Across Flats, 9/16" Overall Height (Pack of 10)

The grade 2 steel self-locking serrated hex flange nut has a zinc plating and meets American Society of Mechanical Engineers ASME B18.2.2 specifications. The nut has a flanged base on one end that eliminates the need for a washer when fastening components. It has a self-locking serrated flange that digs into the material being fastened to help prevent loosening. The body has a hex shape with six flat sides that a wrench can grip to turn from the side, enabling use when there is no space above the nut. Grade 2 steel, composed of either low or medium carbon steel, is often used in applications where toughness is the primary consideration. The zinc plating resists corrosion and has a reflective appearance. Width is measured as width across flats.Nuts are internally threaded fasteners that are used with bolts and threaded rods and studs to connect components. Several different nut styles fit a variety of application and installation requirements. Some styles, such as hex nuts, acorn nuts, flange hex nuts, and coupling nuts, must be tightened with a tool. Others, such as eye nuts, thumb nuts, and wing nuts, can be tightened by hand. Some nuts have a self-locking mechanism, such as a nylon patch or distorted threads, that makes them suitable for applications with a high amount of vibration.
