Product Description

Product Name	Stainless Steel Serrated Flange Nuts
Material	Made from 18-8 stainless steel, these nuts have good chemical resistance and may be mildly magnetic. They are also known as A2/A4 stainless steel.
Shape Type	Hex nut. Height includes the flange.
Application	These flange locknuts have serrations that grip the material surface instead of the threads for easy installation and mild vibration resistance. The flange distributes pressure where the nut meets the material surface, eliminating the need for a separate washer.
Standard	Nuts that meet ASME B18.2.2 or ISO 4161 (formerly DIN 6923) specifications comply with these dimensional standards.
