Product Information

 

Hex Flange Nuts distribute pressure where the nut meets the material surface, eliminating the need for a separate 
washer. 18-8 stainless steel offers excellent corrosion resistance and resists chemicals, most dyes, food and nitric acid. 
Type 316 stainless steel offers superior corrosion resistance than 18-8 stainless steel and resists salt water, acids, 

chlorides, alkalis and other industrial solvents. Both materials maybe mildy magnetic and have a Class 2B thread fit. These 
Hex Flange Nuts meet AMPG 2018 ZNF.01. Height includes the flange.
