Small Parts Steel Hex Nut, Zinc Plated Finish, Class 8, JIS B1181, M8-1.25 Thread Size, 12 mm Width Across Flats, 6.5 mm Thick, 50 Count (Pack of 1)

The class 8 steel hex nut has a zinc plated finish and meets Japanese Industrial Standards JIS B1181 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. Class 8 steel is often used in applications where strength is the primary consideration. The zinc plating resists corrosion 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.
