Steel Flange Nut, Zinc Yellow-Chromate Plated Finish, Grade 8, Self-Locking Nylon Insert, Right Hand Threads (Pack of 25)

The grade 8 steel flange nut has a self-locking nylon insert design and a zinc yellow-chromate plating. The nut has a flanged base on one end that eliminates the need for a washer when fastening components. It has a self-locking nylon insert to help prevent loosening when the nut is threaded to another component. Grade 8 steel is stronger than grade 5 steel and is often used in applications where strength is the primary concern. 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.
