The 18-8 stainless steel hex flange nut has a self-locking serrated flange and plain finish, and meets American Society of Mechanical Engineers ASME B18.2.2 specifications. The nut has a flanged base on one end that eliminates the need for a washer when fastening components and a hex body that tightens from the side with a wrench, enabling use when there is limited space above the nut. The self-locking serrated flange digs into the material being fastened to help prevent loosening. The 18-8 stainless steel material provides strength and offers good corrosion resistance in many environments. The material may be slightly magnetic.
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.
