Small Parts Steel Hex Nut Zinc Plated Finish Grade 5 Asme B18.2.2 1"-8 Thread Size 1-1 2" Width Across Flats 55 64" Thick Pack Of 10

The grade 5 steel hex nut has a zinc-plated finish and meets American Society of Mechanical Engineers ASME B18.2.2 specifications. It has six flat sides that a wrench can grip to turn from the side, enabling use when there is no space above the nut. Grade 5 steel, composed of quenched and tempered medium carbon steel, is often used in applications where strength is the primary consideration.

The zinc plating offers corrosion resistance and has a reflective appearance.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 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.
