Hole alignment tools, methods of making such tools, and methods for aligning holes in a plurality of work pieces are disclosed. The hole alignment tools may exert, when fully engaged with similarly sized, stacked holes, a substantially uniform force against the work piece surfaces that define the holes. The hole alignment tool includes a doweling body having a plurality of radially expandable legs, a housing, and a spreader element. The doweling body legs include a decreasing sectional thickness extending from the distal ends thereof towards the proximal end of the doweling body. Depending upon its state, the radial profile of a doweling body's legs may be converging or parallel for tool insertion and removal, or diverging for alignment purposes.

A ground attachment system (1) for a tire characteristics detection unit (15).sub.7 comprises an attachment plate (2) comprising a plurality of recesses (3) distributed over the surface of the attachment plate, a plurality of frustoconical clamping rings (4), and a plurality of cylindrical guide tunnels (5) arranged in the detection unit (15), the clamping rings (4) and the guide tunnels (5) each comprising a complementary conical portion (6, 7) converging towards the attachment plate (2) when the ring (4) is in the clamping position in a tunnel (5).

An indexing pin comprises a central axis. The indexing pin further comprises a threaded portion, extending along the central axis. The indexing pin also comprises a stem, extending along the central axis opposite the threaded portion. The indexing pin further comprises a cylindrical surface, extending along the central axis between the threaded portion and the stem. The indexing pin further comprises a tapered surface, extending between the threaded portion and the cylindrical surface. The indexing pin further comprises a flange, located between the stem and the cylindrical surface.

The present invention relates to a vehicle body assembly structure allowing a distance between a vehicle body and a part to be adjusted in any of left-right, front-rear, and up-down directions with a simple structure such as a screw.

A compensating fastener assembly is configured to secure a fastener to a surface element. The compensating fastener assembly includes a compression limiter having a cylindrical main body and a flange, the cylindrical main body defining a channel and a longitudinal axis. The compensating fastener assembly further includes a spring defining a central passage. The central passage of the spring is configured to receive the main body of the compression limiter such that a first end of the spring is configured to be disposed adjacent the flange of the compression limiter.

A connection unit for connecting a first component to a second component with a distance in between. The connection unit has a connection screw having a head in the shape of a first ball segment and a shank. The shank has an outer thread. The connection unit also has a base element having: a second outer thread, and a first portion having a first inner diameter; a through-opening is provided at a second axial end and has a second inner diameter which is smaller than the first inner diameter, and an outer side of the base element is in the shape of a second ball segment. The first portion and the through-opening are distanced axially and are connected by a transition portion, which at least partly provides a bearing surface for the head of the connection screw, and the shank extends through the through-opening.

A probe fastening system has a plate having at least one coupling-on recess and having at least one alignment element, which is arranged in the outer region of the plate, a backplate which has a fastening device for the fastening of a static probe and at least one recess which corresponds with the alignment element, at least one peelable shim which corresponds with the alignment element and which is arranged between the plate and the backplate, at least one alignment device which corresponds with the alignment element, and a coupling-on element which defines a cavity and which is designed for isobarically coupling the static probe onto the coupling-on recess.

A mount system for a supporting a plurality of photovoltaic panels includes a plurality of stanchions. Each stanchion is spaced apart from other stanchions in a linear stanchion array having first and second ends. Each stanchion includes a vertical member and a transverse member supported by the vertical member. The transverse member has a plurality of support points. The system includes a plurality of anchor arrangements. A first anchor arrangement is located proximate the first end and a second anchor arrangement is located proximate the second end. The system includes a plurality of cables. Each cable is under tension and extends between the first and second anchor arrangements. Each cables extends to engage and is supported by a support point on a transverse member. The system includes a plurality of photovoltaic panel attachments. Each photovoltaic panel attachment is secured to a point on a photovoltaic panel and to a cable.

The invention provides a radially expanding fastener/alignment plug assembly for use with a torque power tool, the assembly including: a sleeve member (10), insertable into a hole of an object, having radial expansion elements with inner surface portions which are tapered towards a first end; an expanding member (20), insertable in the sleeve member, having an outer surface portion which is tapered towards a first end, cooperating with the inner tapered surface portions of the radial expansion elements of the sleeve member; and a displacement member (30) formed between a second end of the sleeve member and a second end of the expanding member. Advantageously, the assembly is self-reacting allowing an actuation torque to be applied to and reacted upon to create high levels of pulling and expansion force without the need for an external reaction point.

A tolerance compensation arrangement for fastening first and second components with compensation of tolerances between the components. The arrangement comprises a base element having a first element with a first inner thread, a second element with a second inner thread, a supporting element arranged in between, and an adjustment unit with a threaded sleeve with an outer thread and a dragging unit at least partially arranged in the sleeve. The outer thread forms a first thread pairing of a first thread direction with the first inner thread. A fastening screw, can be screwed into the second inner thread via a second thread pairing of a second thread direction opposite to the first thread direction. The fastening screw can be connected to the adjustment unit via the dragging unit so that, during the rotation of the fastening screw, the adjustment unit co-rotates and is moved into abutment with the first component.
