Grade 8 UNF flange locknuts are high-strength, all-metal fasteners with integrated washers, ideal for heavy-duty, high-vibration applications requiring superior clamping force.
These nuts use fine threads (UNF) for high-tension clamping, feature Grade 8 strength, and incorporate a flange to distribute pressure and a locking mechanism (serrations or deformed top) to prevent loosening
