product image

Metric flange nuts are similar to and often used with metric flange bolts and are available with coarse and fine machine screw threads. A large protruding circular flange, the diameter of which exceeds that of the hex section, accommodates oversized holes. Choose from smooth (non-serrated) and serrated bearing surfaces. The serrations provide resistance to loosening.
