(1) The socket wrench guide thread wear is serious, and the pre-compression of the threaded screw sleeve is not in place: the special threaded bottom hole plug gauge for the wire threaded sleeve is used for testing. If the gauge is not limited, the new socket wrench should be used.
(2) The threaded screw sleeve cannot be screwed out of the guiding thread in the mounting wrench sleeve: use the special thread tap of the wire thread sleeve to attack the guiding thread of the mounting wrench again. If not, replace it with the manufacturer.
(3) Some fine teeth specifications are easily installed with T-slot wrenches: skilled operation or replacement of threaded end wrenches.
(4) Threaded head wrench to deform the wire screw sleeve mounting handle: Skilled operation or replacement of T-slot wrench.
(5) If 3 or 4 abnormalities are not solved: custom-made threaded head type and T-slot combined type wrench.
