SWT-F Series LockNut

SWT/F series For SWT/F series locking nut, its brass locking pin forms a angle of 30 degree with the thread. It does not bear the axial load forced on the thread. Once the nut is locked, the thread surface will not release axial load and the nut will not be deformed. Three lock nuts with equal spaces can precisely position the nut, keep it perpendicular to the shaft. F-type nuts can ensure their precision even after multiple assembly and dis-assembly. Material: 42CrMo,45#, 40Cr Hardness: HRC28°—32° Thread Precision: ISO4H Run Out: 0.005mm
