MF rod are made by hollow drill steels; We use advanced production technology CNC and hollow drill steel processing by Boring Method ensuring quality reliability , Optimize processing procedure, entirely automatic threading equipment to finish the thread naturally and reduce the concentration of stress. Shape once of whole heat-treatment ensures long lifespan , Usually for MF rods, there are R32, R38, T38, T45 ,T51,ST58, T60 threads, and different lengths of rods are available from 600mm to 6400mm usually. |
