Overview
This Class 10 carbon steel hex nut is engineered for high-strength, precision assembly in demanding industrial and machinery applications. It features an M52-3 fine thread profile, which offers enhanced vibration resistance and superior load distribution across the engaged threads compared to standard coarse-thread alternatives. The black oxide finish provides a durable layer of protection against corrosion. With a substantial width across flats of 2.047 inches, this nut is built to withstand significant torque and clamping force in critical connections.
Key Features
