Pipe vise are designed for holding pipes, to facilitate operations such as threading or cutting-off to required length.
Figure shows various parts of a pipe vice. To assemble the vice, the screw rod 4 is
screwed into the base 1 from above. When the circular groove at the end of the screw rod is in-line with
the 6 mm diameter transverse hole in the housing, the movable jaw 2 is inserted from below. After
alignment, two set screws 3 are inserted into the jaw. This arrangement allows the jaw to move
vertically without rotation when the handle is operated and the screw is turning.
