An apparatus includes a shaft, a slide lock, and a pin. The shaft includes a first end, a second end opposite the first end and a middle portion between the first end and the second end. The first end includes an enclosure. The middle portion includes a tapered hole. The tapered hole is tapered in a direction from the first end to the second end. The slide lock is disposed over the shaft. The pin is disposed through the tapered hole and coupled to the slide lock. The movement of the slide lock is coupled to movement of the pin within the tapered hole of the shaft. The position of the pin within the tapered hole corresponds to an amount of opening of the enclosure.

The present disclosure relates to an insert and system of installing the same. The insert includes a tapered core and a cylinder. The core releasably secures to an installation device which includes a depth stop or a depth control to control the installation depth of the insert. The insert may be provided in a tray that allows for easier handling of the inserts and installation thereof in installation holes, for example in a hydraulic manifold. In some cases, the core includes a threaded hole to releasably secure the insert to the installation device, thus allowing the installation device to pull the core into the cylinder. The core and cylinder may be made of metallic materials such as steels, steel alloys and others. In some cases the insert can withstand blow out pressures of 40,000 psi or higher.

A tool for removing a brake shoe key having a main member and a pin. The main member has an elongated section with one end connected to a receiver. The receiver forms a trough for receiving a brake shoe key. The longitudinal axis of the trough is parallel to the longitudinal axis of the elongated section of the main member, which has at least two holes that for receiving an end of a pry bar. The first side wall and the second side wall of the trough each has an opening that is configured to allow the elongated body of the pin to pass through both openings simultaneously. The first side wall is contiguous with the elongated section of the main member. The floor of the trough forms a front side of the tool, which has a slot for receiving a tip of a brake shoe key.

A dismantling tool comprises a main body, a pushing mechanism, and an insertion hole. The pushing mechanism includes a driving portion and a pushing portion. The driving portion is located at the main body. The pushing element is movably screwed with the driving portion. The insertion hole is formed on the main body for a handtool to insert therein for engagement.

A chain and lever post puller system for pulling 2 inch by 4 inch stakes from the ground. The apparatus may also pull round posts or tee-posts with a minimum of effort and with no prior digging. The chain and lever post puller system is a first class lever, requires no heavy equipment or hydraulics, and is easily transportable by hand. The puller comprises a vertical column to which the pivot lever is removably connected via a hinge, which also forms the fulcrum for the pivot lever. A first end of a chain is attached opposite the handle to the end of the pivot lever, and a self-tightening post grip is attached to the second end of the chain. A downward force is applied to the proximate end of the pivot lever when the post grip is attached to a stake to remove the stake via mechanical advantage.

A bit holder can include a body and a collar. The body can be mountable to a rotor of a piece of equipment. The collar can be coupled to the body and can be configured to receive the bit therein. The collar can include a first flat collar surface forming a portion of a radially outer surface of the collar and a second flat collar surface forming a portion of the radially outer surface of the collar.

A torque wrench is provided. The torque wrench has housing and a rotating assembly rotatably mounted in the housing. The rotating assembly has a gripping assembly with an aperture for receiving a tubular and a plurality of die assemblies; a bevel pinion carrier assembly with a bevel pinion carrier and a bevel pinion mounted in the bevel pinion carrier; an upper ring gear fixed to an upper bevel gear rotatably connected to the bevel pinion at an upper side of the bevel pinion carrier; a lower ring gear fixed to a lower bevel gear rotatably connected to the bevel pinion at a lower side of the bevel pinion carrier; and first and second members threadably coupleable with each other, the first threadably coupleable member fixedly connected to the bevel pinion and the second threadably coupleable member drivingly connected to the die assembly, wherein rotation of the bevel pinion drives the die assembly toward and away from the tubular.
