Small Parts Steel Hex Nut, Cadmium Plated Finish, Grade 8, Mil. Spec. MS51967, 1/2"-13 Thread Size, 3/4" Width Across Flats, 7/16" Thick (Pack of 10)

The grade 8 steel hex nut has a cadmium plating and meet United States Military Standard Mil. Spec. MS51967 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 cadmium plating offers corrosion resistance, especially in marine and alkaline environments, and provides lubricity.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.
