Metric 18-8 Stainless Steel Serrated Flange Locknuts
These flange locknuts have good chemical resistance and may be mildly magnetic. They 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. Height includes the flange. Metric 18-8 stainless steel is also known as A2 stainless steel.
