Small Parts FSC14HN8ZY Steel Hex Nut, Zinc Yellow-Chromate Plated, Grade 8, ASME B18.2.2, 1/4"-20 Thread Size, 7/16" Width Across Flats, 7/32" Thick (Pack of 100)

The grade 8 steel hex nut has a zinc yellow-chromate plating 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 8 steel, composed of quenched and tempered medium carbon alloy steel, is stronger than grade 5 steel and is often used in applications where strength is the primary consideration. The zinc yellow-chromate plating offers good corrosion resistance.

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.
