During washer flattening, the bottom serrations extend their bite radially inward and underneath the nut or bolt head. The Belleville spring action may secure the nut or bolt head on top against inadvertent loosening. In addition, a dual washer stack may include a conical ramp interface for a low overall height and lock washer functionality. Radial torque receive faces remain in plane during washer flattening and receive the torque substantially free of radial force components. A radially slim reaction socket interface may thus be tapered down around them without need for continuous circumferential structural support.

CONCENTRIC ACTUATION AND REACTION TORQUE TRANSFER SYSTEM

An actuation and reaction socket tool features a reaction coupling that is slid onto the spline flange of a power torque wrench prior to attaching the actuation socket on the drive shaft of the torque wrench and prior to securing it with a well-known safety pin. The reaction coupling is then coupled to the reaction socket via circumferentially arrayed and interlocking castles on both the reaction coupling and reaction socket. A lock plate spring loaded snaps into grooves on the inside of the castles and axially locks the reaction coupling with the reaction socket. At least one of the reaction coupling and reaction socket is axially withheld by the central actuation socket such that the entire tool system remains connected to the torque wrench. To remove the tool again, the reaction coupling and reaction socket are first decoupled, which provides access again to the safety pin for its removal. 1.

INTERCHANGEABLE, DEBRIS INSENSITIVE AND NON-SLIPPING REACTION TORQUE TRANSFER SYSTEM

Interchangeable monolithic or stacked Belleville reaction washers initially penetrate with outward bottom serration edges only during manual pre-tightening. Slippage is thereby avoided at begin of the consecutive power torque wrench assisted full tightening of the nut and/or bolt head resting on it. As the load ramps up, the reaction washer or stack flattens out and the bottom serrations gradually penetrate radially inwards. Reaction and actuation sockets of varying sizes matching a broad range of reaction washers and nut and/or bolt heads may be interchangeably snapped on a reaction coupling connected to the torque wrench housing. A clearance undercut underneath the reaction washer torque receiving flanges captures eventual debris to further assist unimpeded and fast coupling of the system. Radially oriented contact faces between reaction washer and reaction socket provide a snug contact unaffected by their toroidal movement during washer flattening and a force transfer free of radial force components. 1. An interchangeable actuation and reaction torque transfer system comprising:a. a torque transfer axis; i. a drive shaft torque interface on a first axial actuation socket end for coupling with a torque drive shaft; and', 'ii. an actuation interface on a second axial actuation socket end that is opposite said first axial actuation socket end for coupling with an actuation receiving structure;, 'b. an actuation socket comprising i. a torque wrench interface on a first axial coupling end for coupling with a torque wrench housing; and', 'ii. a reaction socket interface on a second axial coupling end that is opposite said first axial coupling end;, 'c. a reaction coupling comprising i. a coupling interface on a first axial reaction socket end for coupling with said reaction coupling; and', 'ii. a drain interface on a second axial reaction socket end that is opposite said first axial reaction socket end;, 'd. a reaction socket comprising i. a reaction washer axis;', 'ii ...

Adhesive insert anchor

An adhesive insert anchor including an anchor body and a screw member for insertion into a drilled hole in a substrate containing an adhesive. The anchor body further including an integral friction segment and an adhesion segment. The friction segment includes an internally threaded cavity in which to receive the screw member and a knurled portion. The adhesion segment includes a cylindrical section and a plurality of saucer-shaped buttons positioned along its length ending with a terminal button. The buttons on the adhesion segment provide greater surface area for contact between the adhesive and the anchor. The friction segment has an external diameter substantially the same as the diameter of the hole drilled in the substrate, thereby providing a friction fit between the anchor body and the walls of the substrate hole. The external diameter of the adhesion segment is smaller than the external diameter of the friction segment so that when the anchor body is inserted into the hole in the substrate, there is space between the adhesion segment and the walls of the hole which is completely filled by adhesive so as to securely bond the anchor body with the substrate. The friction fit of the friction segment maintains the adhesion segment of the anchor body a proper distance from the bottom of the substrate hole and provides for light-duty loading of the anchor while the adhesive cures.

Tamper-resistant fastener and method and tool for use with same

A fastener includes a round, blind hole or pocket in its head. Installation and removal of the fastener is accomplished with a tool containing an eccentric segment on the end of a shaft. When rotated within the pocket, the eccentric segment displaces laterally relative to the shaft to provide a friction grip to the lateral wall of the pocket. The strength of the grip is proportional to the applied torque. Eccentric displacement allows rotation but prevents the tool from spinning out of the fastener thereby eliminating cam-out and surface damage resulting from contact with a spinning tool tip. The eccentric head of the tool can be made disposable and to shear off when a predetermined torque is reached. The smooth-sided round hole offers no purchase for commonly available tools; making the fastener tamper-resistance. In another embodiment, the fastener includes a raised portion in the pocket. A tool having a complementary opening shears off the raised portion at a predetermined torque.

Angularly shifted three-dimensional cooperation elements i.e. grooves, are connected to corresponding three-dimensional cooperation elements of a tool for unscrewing the base plate. An independent claim is also included for a tool for unscrewing a base plate of a self-breakable nut comprising an unscrewing head.

Antitheft lock for vehicle wheel nut - has adaptor to house nut with top comprising cup with blind holes in bottom engaged by lugs on spanner

The anti-theft shield is used on a vehicle wheel nuts, comprising an adaptor (1) which is fixed onto the nut. The bottom (1b) of the adaptor incorporates blind holes (1e) engageable by pins (6) projecting from a special drive spanner (2), the number of holes equalling the number of pins. The geometrical layout of the holes matches that of the pins and can have equal or unequal hole spacings, together with angular or radial offsetting. The holes are set inside a collar (1g) to deny thieves access to the holes. The central area (1h) of the bottom surface may be raised by a nominal bevel, the tool head being locally recessed (2d) to accommodate the raised area with clearance.

Assembly device

Anti-theft device for securing nuts or bolts of e.g. motor vehicle wheels

The anti-theft device comprises a nut (3) operable only by a special driver (8). This driver may be turned by a spanner acting on the bolt head (9), to drive the nut by means of pegs (6) fitting into corresponding holes (5). The nut, with a cylindrical body, is tightened on the thread (2) to hold the wheel or item (4) against the seating surface (1). The pegs and holes are arranged in a pattern unique to the particular driver and nut set. A cup (10) is a loose fit around the neck of the nut, and prevents the use of any form of grips or pliers to turn the nut. A metal or plastics trim may be fitted over the mouth of the cup.
