Lock nut introduction and nut classificatio

Lock nut is one of the anti-loosening measures. The manufacturing process of fastener lock nut is: material modification cold head , Chamfering and center hole-drilling and deburring, tapping, dephosphorization, heat treatment, grinding, thread, diameter rolling thread on the threaded hole-(pickling) oxidation treatment-defect detection, demagnetization-(pickling) oxidation Handling-coating, inspection, packaging library. Nut material: carbon steel, stainless steel, copper, alloy, etc.
