The present disclosure relates to a method for use in installation of a mill liner, the method including (a) retaining a mounting bolt at least partially within a liner opening extending through the mill liner, (b) positioning the mill liner against a mill shell so that the retained mounting bolt is aligned with a mill shell opening extending through the mill shell, (c) selectively coupling an extraction tool to the mounting bolt, the coupling performed by an operator outside of the mill shell, (d) detaching the mounting bolt from the liner using the extraction tool; (e) pulling the mounting bolt through the mill shell opening so that at least a portion of the mounting bolt protrudes outside of the mill shell, and, (e) securing a fastener onto the mounting bolt to thereby attach the mill liner to the mill.

A tension lever includes an outer body including a top, a bottom, and a plurality of outer body sides including a first outer body side and a second outer body side opposite to and facing the first outer body side, the first outer body side having a substantially planar surface extending along a first direction and a second direction crossing the first direction, an upper first opening defined in the top and defining an upper inner body that extends along the second direction, a lower first opening defined in the bottom and defining a lower inner body that extends along the second direction, a second opening defined in the first outer body side and the second outer body side, the second opening defining a channel that extends along a third direction crossing the second direction, and a barbell including a shaft and a pair of beads at opposing ends of the shaft, the barbell being received in the second opening.

An attachment assembly for being connected with a hand tool includes an active unit, a passive unit and a switching shaft. The active unit includes a front wheel, a middle wheel and a rear wheel are simultaneously rotatably connected in sequence. The passive unit includes a first wheel and a second wheel are simultaneously rotatably connected. The switching shaft pivotably connects the active unit and the passive unit, and switches the active unit and the passive unit being rotatable or not.

An insertion tool for performing an operation on equipment, the insertion tool including: a plurality of segments, each segment of the plurality of segments including a body including: a first hinge; a second hinge, the first and second hinge members pivotally coupling adjacent segments of the plurality of segments together; and a cavity extending along the body of the segment, the cavity exiting the body at a plurality of exit locations, wherein at least one of the plurality of exit locations is disposed adjacent to the first hinge; and a selectively rigidizable strength member disposed within the cavity.

A light bulb remover extracts a broken light bulb from a socket of a high-hat light fixture. The light bulb remover has an extension pole and an extractor head attached to the extension pole. The extractor head has a guide which defines an outer circumference of the extractor head and a bulb extractor configured for engaging in a base of the broken light bulb and creating a friction connection with the base of the light bulb. The bulb extractor is surrounded by the guide, and the guide has a diameter being less than a diameter of the high-hat light fixture and dimensioned so that when the light bulb remover is disposed within the high-hat light fixture the bulb extractor is self-aligned with a middle area of the base of the broken light bulb.

Disclosed herein are devices, systems, and methods of an adjustable crowfoot wrench for use with large format fasteners such as bolts or hydraulic line nuts over 1 inch in size. The adjustable crowfoot wrench includes a base, a translating arm, and a gear. The translating arm include one or more fastener pads and a threaded translating shaft. The gear is configured to threadably engage the threaded translating shaft of the translating arm. The threaded translating shaft is configured to be received by and translate through a translating channel of the base. The base also includes a stationary pad, a drive aperture and gear retaining arms. The gear is retained by the gear retaining arms of the base when the gear is threadably engaged with the translating arm within the base.

A packing screw removal tool for removing packing from a pump fluid end comprising: a tool body; a plurality of packing screw engagement dogs distributed about an axis of rotation about the packing screw removal tool; and a torque transfer engagement post coupled to the tool body. The engagement dogs align with and are releasably connected to radial locations on the packing screw. Applied torque is transferred through a torque transfer engagement post, through the tool body to the engagement dogs and into the packing nut. A second torque transfer engagement post is smaller than the first engagement post. The shape of the tool body allows rotation in limited or confined space. A pump may be serviced at the wellsite by utilizing the packing screw removal tool to unthread the packing screw from the fluid end.

A faucet installation tool includes at least two coupling units. Every adjacent two of the coupling units are detachably connected together. A hollow area is formed between middle portions of the coupling units. Tops of the coupling units are formed with a first socket portion. The first socket portion is configured to receive a lock nut used for installing and fixing a threaded connecting pipe of a faucet, improving the connection strength between the first socket portion and the lock nut. The faucet installation tool does not require a large lateral space and is convenient to tighten the lock nut when in use.

A hex tool including a hex head having a hex portion for engaging socket head cap screws or wrenches. The hex portion also having a body portion extending from the hex portion. The body portion having a spherical-shaped cavity disposed therein. The hex tool also includes a handle with a ball end and a primary handle portion. The ball end disposed in the spherical-shaped cavity to provide the hex tool a significant range of motion during use. Another type of hex tool having a hex head having a hex cavity for engaging a hex head bolt. The hex head also having a body portion extending from the hex cavity. The body portion having a spherical-shaped cavity disposed therein. The hex tool also including a handle with a ball end and a primary handle portion. The ball end disposed in the spherical-shaped cavity to provide the hex tool a significant range of motion during use.

A stop valve adaptor to make a stop valve having a threaded stem actuatable through a stop valve box using a stop valve key. The stop valve adaptor is affixed to the threaded stop valve stem using a nut. The stop valve box is preferably made of a polymeric material and is maintained at a predetermined length by using friction due to O-rings, a glue joint, or clamping to dispose a stop valve box cover at the ground surface.
