Metric Serrated Flange Nuts (DIN 6923), A4-70 Stainless

METRIC STAINLESS A4 (316) HEX SERRATED FLANGE LOCKNUT, DIN 6923

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.
