Product Details

Name:stainless steel 18-8 or A4 Hex Flange lock nuts, Hexagon Flange Nut Unserrated Standard: DIN 6923 ISO 4161, Hexagon Flange Nut serrated Standard: DIN 6923 ISO 4161


Descriptions: Hex nut with an enlarged circular base flaring out from the bottom of the nut. The bearing surface of the flange has serrations which displace material on the mating surface when the nut is wrenched into place, forming a connection which resists loosening.


Applications: Requires a greater amount of torque to loosen than to tighten the nut. Will span oversized or poorly aligned holes. Flange provides a more uniform bearing-stress to clamp-force ratio than other low carbon lock nuts. Does not gall screw threads.
