A hook spanner has a spanner body having two opposite side surfaces, a handle segment, and a hooking segment formed on an end of the handle segment. The hooking segment has an abutting end surface located away from the handle segment and having an abutting end surface extending obliquely from one of the two opposite side surfaces of the spanner body to the other side surface. The hook spanner is adapted to turn a nut having multiple grooves arranged around the nut. Each groove has an inclined surface extending obliquely and inwardly from a peripheral surface of the nut. The abutting end surface is aligned with the inclined groove surface of one of the grooves of the nut to stably turn the nut.

A fire hydrant wrench includes a wrench-head able to fasten to the pentagonal interface of a fire-hydrant and a handle able to be selectively extended or retracted by a user. The wrench includes a cylindrical rod which may be contained by and telescopes within a tubular handle. A cap on a handle-end of the tubular handle prevents the cylindrical rod from leaving the handle in one direction, while a collar affixed externally to the cylindrical rod prevents it from leaving the handle in the opposite direction. The tool-head containing the wrench is affixed to a tool-end of the cylindrical rod which protrudes from the tubular handle in all positions.

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.

A wrench for opening and closing a clamp having a lever includes a handle section, a leverage section, and a locking assembly. The leverage section is coupled to the handle section. The leverage section includes an engagement surface to engage the clamp and an opening formed therein, the opening being configured to receive the lever of the clamp therein. The locking assembly is coupled to the leverage section. The locking assembly is configured to releasably secure the leverage section to the lever of the clamp when the lever is received within the opening of the leverage section.

A tool for controlling a controlled element of a height adjustable foot of a furnishing item and the like includes an engagement portion and a handle coupled to the engagement portion and having two arms shaped to embrace an outer edge of the height-adjustable foot and keep the engagement portion associated laterally with the adjustable foot. The engagement portion is arranged between the two arms and includes a toothed section that extends over a rounded area of the surface between the two arms of the handle so as to engage radial septa or seats defined in the controlled element and converging toward a central axis of the adjustable foot. The toothed section is shaped as an arched and rounded tooth extending toward one of its free ends in the direction from one arm to the other.

A torque operable conduit union and mating spanner wrench are shown for the hammerless coupling of the ends of abutting fluid conduits, such as pipe, hoses, and fittings. A union nut body has an upper peripheral planar face, a lower peripheral planar face and a circumferential side wall. The circumferential side wall has a series of protuberances extending outwardly therefrom which define at least two circumferentially spaced wrench receiving formations. Each of the wrench receiving formations includes a slot portion which communicates with a transverse opening portion of the formation. The mating spanner wrench has a bridge region which spans certain of the receiving formations and engaging tangs which engage the slot portions of the formations for applying torque to the union nut.

The present specification discloses a locking fastener that includes a first threaded fastener axially positioned within an axial through hole of a second threaded fastener, and captured therein by a rotating joint that permits rotation of the first threaded fastener and the second threaded fastener relative to one another about a common thread axis. In one or more embodiments, the first threaded fastener thread handedness is opposite to the second threaded fastener thread handedness. Additionally disclosed, is a screwdriver tool configured to simultaneously engage and oppositely rotate the first threaded fastener and the second threaded fastener into a mating component having a first mating thread and a second mating thread configured to receive the first threaded fastener and the second threaded fastener, respectively, driven at the same axial advance distance for each turn. Once tightened, the present locking fastener resists loosening and provides a tamper-resistant hold.

A drain removal tool with a central opening aligned along a central tool axis, a holding section with a hex head for applying torque to the tool, and an engagement section including elongate sharp ridges or teeth extending in a helical pattern from an external surface of the engagement section from the tool for engagement with the drain to be removed. Each elongate sharp ridge has one flat face and a ramp face. Each flat face is aligned along a radius extending outwardly from the central tool axis. The ridges are spaced such that the distance between each flat face is approximately 6 degrees. Each helical ridge is a left hand helical serration on a 15 degree pitch with respect to the central axis of the central opening. The holding section includes a hex head configuration. The central opening in the holding section has a hex configuration.

A hand tool includes a handle section, a working end operably coupled to the handle section, and a jaw assembly disposed at the working end. The jaw assembly includes a movable jaw and a fixed jaw. A span defined between the movable jaw and the fixed jaw is adjustable. Each of the movable jaw and the fixed jaw includes an array of teeth defined by ridges that extend substantially parallel to each other. The array of teeth on each of the fixed jaw and the movable jaw includes a first set of teeth having a first width and a first depth, and a second set of teeth having a second width and a second depth. The first depth is less than the second depth and the first width is less than the second width.
