A T-handle is more compact. This type of wrench uses a collet to secure the tool. The collet design has two pieces: a threaded "nosecap" and four collet fingers; the collet fingers thread on the outside and the nosecap is screwed onto them. The nosecap is tapered, which causes the fingers to clamp onto the tool.
A die cuts an external thread on cylindrical material, such as a rod, which creates a male threaded piece that functions like a bolt. Dies are generally made in two styles: solid and adjustable. An adjustable die may be adjusted either by an integrated screw or by a set of screws set in to the die holder (termed a "die stock").
thread rolling screws: These have a lobed (usually triangular) cross-section. They form threads in a pre-existing hole in the mating workpiece by pushing the material outward during installation. In some cases the properly prepared hole in sheetmetal uses an extruded hole. The extrusion forms a lead-in and extra thread length for improved ...
The design of the adjustable jaw, which permits a certain amount of intentional play out of square, allows it to bind on the pipe, with forward pressure on the handle pulling the jaws tighter. On some models, two leaf springs, above and below the knurled adjusting knob, help unlock the jaw when pressure on the handle of the wrench is released.

A screw must always be turned to assemble the joint.
