A tool for unscrewing a stud has a body with cam surfaces in a bore. A recess extends through the cam surfaces. Jaws have outer sides in engagement with one of the cam surfaces and inner sides containing teeth. An outward protruding rib on the outer side of each of the jaws inserts into the recess. Rotation of the body in a first direction causes the cam surfaces to slide in the first direction along the outer sides of the jaws, pushing the jaws to a gripping position. Rotation of the body in a second direction causes the cam surfaces to slide in the second direction along the outer sides of the jaws, enabling the jaws to move to a retracted position.

An apparatus for applying torque to a body includes a base defining an inner chamber. The apparatus includes a plurality of pins supported by base and disposed in the inner chamber, the plurality of pins moveable relative to the base between engaged positions and disengaged positions. The apparatus includes a trigger actuatable to move at least one of the plurality of pins to the disengaged position.

A Spline Wrench is disclosed for manually rotating clockwise and engaging a power take off (“PTO”) drive shaft of a tractor, truck, aircraft, or watercraft having six or more splines for aligning the PTO with a female coupling of a machine, tool, or equipment, such as a mower, tiller, combine, water pump, air pump, fuel pump, compressor, generator, or other similar machine, tool, or equipment. The apparatus is used to rotate clockwise and align the splines of a spline shaft manually without having to engage the engine and transmission and pulsing the shaft to rotate it into position. Various embodiments of the Spline Wrench are designed to engage the splines of a Type 1 540 RPM 1 3/8 in. diameter 6-spline shaft, a Type 2 1000 RPM 1 3/8 in. diameter 21-spline shaft, a Type 3 1000 RPM 1 3/4 in. diameter 20-spline shaft, and a Type 4 1300 RPM 2 1/4 in. diameter 22-spline shaft.

An oil filter wrench having a base, a main gear, a plurality of claws each having a gear portion and an arm configured to engage an oil filter. The gear portions are rotatably disposed within the base and configured to engage the main gear such that when the main gear rotates; the arms correspondingly extend or contract relative to the base. The oil filter wrench also includes a main spring. The main spring is disposed within a cavity defined by the main gear. The main spring is configured to selectively bias the main gear toward rotation in either a first direction or a second direction opposite to the first direction. The oil filter wrench is characterised in that it also includes a switching mechanism a switching mechanism. The switching mechanism is configured to selectively toggle between a first position and a second position. In the first position, the switching mechanism engages a first tine of the main spring such that the main gear is biased to rotate in the first direction. In the second position, the switching mechanism engages a second tine of the main spring such that the main gear is biased to rotate in the second direction. The switching mechanism is toggled between the first and second positions by respectively engaging a first pin or a second pin that is integrated into one of the plurality of claws.

A removal tool for a screw-on canister filter comprising a plurality of a tooth and side apertures. The tooth comprises of a chisel edge, bevel surface, and receding surface. The chisel edge of each tooth has an interference fit to the filter and it located on the center of a filter scallop. The side apertures allow the metal canister of the filter to contort and grant access to the filter bottom.

An angle valve wrench configured for use in rotating an angle valve, the angle valve wrench having a body with a first end and a second end, defining a length L1. The body also has an outside surface and a central axis that is parallel to the length L1 and that passes through the first and second ends. A notch is formed at the first end that corresponds to an angle valve handle. A gripping element is formed on the outside surface of the wrench near the second end. A user places the notch of the wrench over a conventional angle valve from a standing position and rotates the wrench about the central axis, causing the angle valve handle to rotate.

An oil filter wrench having a base, a main gear, a plurality of claws each having a gear portion and an arm configured to engage an oil filter. The gear portions are rotatably disposed within the base and configured to engage the main gear such that when the main gear rotates; the arms correspondingly extend or contract relative to the base. The oil filter wrench also includes a main spring. The main spring is disposed within a cavity defined by the main gear. The main spring is configured to selectively bias the main gear toward rotation in either a first direction or a second direction opposite to the first direction. The oil filter wrench is characterised in that it also includes a switching mechanism a switching mechanism. The switching mechanism is configured to selectively toggle between a first position and a second position. In the first position, the switching mechanism engages a first tine of the main spring such that the main gear is biased to rotate in the first direction. In the second position, the switching mechanism engages a second tine of the main spring such that the main gear is biased to rotate in the second direction. The switching mechanism is toggled between the first and second positions by respectively engaging a first pin or a second pin that is integrated into one of the plurality of claws.
