Detail & Specs
These nylon insert locking flange nuts have a serrated underside. The serrations on the bottom of the flange provide a locking action, digging into the parent material when tightened down and able to withstand extreme vibrations without loosening. Serrated flange nuts are meant to permanently mar the material they are installed against.
The flanged form acts as a built-in washer to evenly distribute force over a larger area. This nut does not damage the threads of bolts or screws and can be reused a limited number of times. Not recommended for higher temperature installations. Nylon insert color tone varies.
