Claim 0:
1. An adjustable pliers with thread-engaging means comprising:
water pump pliers and a thread-engaging means;
wherein the water pump pliers are slip joint pliers whose fulcrum is moved to modify a distance that jaws opens;
wherein the jaws are angled with respect to a central axis of the water pump pliers;
wherein the thread-engaging means comprises arcuate grooves that are longitudinally oriented on a first jaw and on a second jaw;
wherein the thread-engaging means is operable to grasp a threaded element that is held between the first jaw and the second jaw and is laterally oriented relative to the water pump pliers without damaging threads of the threaded element;
wherein the water pump pliers comprise a first handle and a second handle, collectively referred to as handles;
wherein the first jaw comprises a first flat serrated surface and a first curved serrated surface and the second jaw comprises a second flat serrated surface and a second curved serrated surface, wherein the flat serrated surfaces and the curved serrated surfaces are located on the bottom of the respective jaw, wherein the flat serrated surfaces are closest to the distal end of the respective jaw, wherein the flat serrated surfaces are planar surfaces, wherein the flat serrated surfaces, each comprises a set of teeth that are laterally oriented across the respective flat serrated surface, wherein the curved serrated surfaces are located adjacent to the respective flat serrated surface on the proximal side of said respective flat serrated surface, wherein each of the curved serrated surfaces, is a singly-curved surface oriented to show a convex curve when viewed from a side of the water pump pliers and wherein each of curved serrated surface comprises a set of teeth that are laterally oriented across the respective curved serrated surface;
wherein the thread-engaging means comprises a first threaded surface located on the first jaw and a second threaded surface located on the second jaw such that the first threaded surface opposes the second threaded surface;
wherein the first threaded surface is located adjacent to the first curved serrated surface on the proximal side of the first curved serrated surface, wherein the first threaded surface is a singly-curved surface oriented to show a convex curve when viewed from a side of the water pump pliers and wherein the first threaded surface comprises a set of threads that are longitudinally oriented along the curve of the first threaded surface;
wherein the second threaded surface is located adjacent to the second curved serrated surface on the proximal side of the second curved serrated surface, wherein the second threaded surface is a singly-curved surface oriented to show a convex curve when viewed from a side of the water pump pliers, wherein the second threaded surface comprises a set of threads that are longitudinally oriented along the curve of the second threaded surface; and
wherein the first threaded surface and the second threaded surface engage with the threads of the threaded element that is placed laterally across the thread-engaging means such that the threaded element is held between the first threaded surface and the second threaded surface.
