A non-magnetic locking sleeve includes an engagement unit disposed in a body which includes a locking socket and a positioning groove. The locking socket is enclosed by a plurality of peripheral walls connected one after another for holding a fastener. The positioning groove is annularly recessed into the peripheral walls for receiving the engagement unit. Preferably, an intersection of two adjacent peripheral walls forms a recessed portion whereby the fastener is held by the peripheral walls more tightly while inserting into the locking socket. A periphery of the engagement unit can be formed with a rough surface or at least one engaging surface to increase a contact area between the engagement unit and the fastener. Accordingly, the fastener is firmly positioned by the locking sleeve to increase the stability of a following fastening operation executed by the fastener.

A connecting element, preferably for fastening a wheel, or rim, to a hub of a vehicle, includes a body having a respective outer perimeter surface which extends along a respective imaginary profile, in particular an imaginary circular profile, there being formed, at the perimeter surface, respective elements for the engagement of corresponding elements or tool for screwing and/or unscrewing the connecting element, and screw thread elements for fastening, preferably to the vehicle hub. The engagement elements include a plurality of perpendicularly extending and circumferentially distributed engagement troughs which are recessed relative to the imaginary outer profile and each being separated from the adjacent trough by a respective outer perimeter transit zone. The outer transit zone has a width (r) which is less than the width (i) of the trough, and in particular, a width (r) which is less than half the width of the trough.

A screw removal tool includes an extension shaft configured to be insertable into a universal screwdriver for torquing use and a body configured to couple to and remove a damaged screw via engagement of said damaged screw with an internally toothed extraction fitment configured to engage a peripheral surface of a screw head of a damaged screw such that a grip-friction is impartable upon said screw head.

Torque adapter for a cable connector that expands to fit connector nuts of different sizes. The adapter fits around the cable connector and engages three of the corners of a hex nut with matching recessed regions in its inner surface. It has three slots that receive the other three corners of the connector nut. The adapter is flexible so that the slots may widen to accommodate connector nuts of larger widths. The outer surface may be hexagonal so that a wrench or similar tool may be used to turn the torque adapter.

A screwing tool for an impact wrench for screwing wheel nuts onto and off from a hub body for securing a vehicle wheel, having a main body, which has an open side oriented toward the wheel nuts and which includes a hollow profile. The hollow profile has a tool contour, which is arranged on the open side and can be brought into engagement with a wheel nut contour. At least one peripheral control edge is remote from the open side for releasing a retention element. The control edge has a circular arc region with a constant control edge height h.sub.1 and a cam region with a control edge height h.sub.2 that decreases continuously and then increases again continuously. Height h.sub.1 is equal to h.sub.2 in the respective transition of the circular arc region and the cam region, such that the geometrical shape of an oval is reproduced in cross section.

Disclosed is a tightening tool for a screw element, having a tool receptacle and an associated line. A coupling part is provided, which is formed at a free end for engaging with the tool receptacle in a form-closed manner and transitions into a handle or can be coupled to a handle at the other end. The coupling part has an interior and at least one lateral opening for inserting or leading out the line at least at the free end of the coupling part. The interior and the opening extend to the free end and are open there. The invention further relates to a coupling part and to a screw element.

A fastener extractor tool is an apparatus that is used to remove a seized or damaged fastener. The apparatus may include at least one shank body and at least one torque-tool body. The at least one shank body allows the apparatus to be attached to an external torque tool. The torque-tool body engages the seized fastener to apply torque to dislodge said seized fastener. The at least one torque-tool body may include a plurality of laterally-bracing sidewalls and at least one engagement feature. The plurality of laterally-bracing sidewalls engage with the seized fastener to efficiently transfer torque from the external torque tool to the seized fastener. The at least one engagement feature is an engagement cavity that forms at least one engagement tooth on the at least one torque-tool body. The at least one engagement tooth engages the seized fastener to ensure torque is transferred to the seized fastener.

The “Sink Faucet Multiple Tool”, is designed so that on one side it can install or remove two types of faucet nuts that fix the faucet to the underside of the sink or lavatory, and on the other side it can install or remove the faucet nut that connects the flexible water hoses to the faucet. It is designed to be easy to use and inexpensive.

A device for removing a boat drain plug, having a body with a distal end and a proximal end. The distal end has a first square-shaped opening configured to engage a boat drain plug. The first square-shaped opening features a first notch extending outward from one side and a second notch extending outwardly from a diametrically opposed side. The proximal end has a first handle extending laterally outward from the body, a second handle diametrically opposed to the first handle and extending laterally outward from the body, and a second square-shaped opening disposed between the first handle and the second handle. The second square-shaped opening is configured to engage a socket wrench.

Stuffing box rebuild systems including a first socket precision-tooled to couple with a top seat of the stuffing box, a second socket precision-tooled to couple with a bottom seat of the stuffing box, and a rebuild table including one or more receptacles for receiving and retaining the stuffing box during the rebuild. In some examples, the stuffing box rebuild system includes a top wrench precision-tooled to couple with a top seat of the stuffing box and a bottom wrench precision-tooled to couple with a bottom seat of the stuffing box. In some further examples, the top wrench is precision-tooled to couple to the first socket and the bottom wrench is precision-tooled to couple to the second socket.
