High-Strength Steel Flange Nuts—Grade 8
A flange distributes pressure where the nut meets the material surface, eliminating the need for a separate washer. Made from Grade 8 steel, these nuts are about 25% stronger than medium-strength steel flange nuts. Height includes the flange.
Zinc-plated, zinc yellow-chromate plated, and black-phosphate steel nuts resist corrosion in wet environments.

High-Strength Steel Serrated Flange Locknuts—Grade 8
Serrations 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. They're about 25% stronger than medium-strength steel flange locknuts. Height includes the flange.
Zinc-plated steel flange locknuts resist corrosion in wet environments.
