A tool for insertion and extraction of temporary fasteners that enables by a plurality of retractable elements, an automatic engagement of the tool on the head of the temporary fastener, without the need for any rotation of the tool with regard to the head, and by lockable grasping units, operated internally locking elements, a high retention and extraction force is achieved, favouring the elimination of the risk of the clamp detaching itself from the tool, enabling control of the entire insertion and extraction process of temporary fasteners. Rapid, effective automation of the use and procedure of the temporary fasteners can be achieved, improving economic profitability and the reliability of their use.

In an exemplary embodiment, a fastener installation tool for installing hidden fasteners to a distal workpiece is provided. The fastener installation tool may include a housing containing an advancement mechanism for moving a plurality of hidden fasteners and a driving member that is engageable with a foremost fastener of the plurality of hidden fasteners to fasten the foremost hidden fastener to a structural member. The advancement mechanism may include at least a wheel, a carriage, and a linkage member. The linkage member may be connected to the driving member and the carriage such that when the driving member moves towards the foremost hidden fastener, the carriage rotates in a first direction, and when the driving member moves away from the foremost hidden fastener, the carriage rotates in a second direction, opposite the first direction, and further causes the wheel to rotate and move a subsequent hidden fastener into position for fastening.

Motor-driven portable tool configured so as to ensure the expansion of a wall anchor (Ch) of a screw (Vs) and wall anchor (Ch) set, with fine setting of the determined stroke of the effector.

A self-drilling expandable anchor installation tool operable with a self-drilling expandable anchor.

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 fastener installation tool and method for interference fit, said fastener (10) comprising a head and a grasping element, said tool comprising a first body (30) extending along a first main axis and having: —at least one load-reacting surface, of which one also constitutes a surface for the application of a load; —a load transmission surface, and—a housing extending along the first main axis from a first end of said first body, said housing being extended along the first main axis by a drilling extending from said housing as far as a second end of said first body. According to the invention, the load transmission surface is situated at the second end of the first body (30) and extends perpendicular to the first main axis, said load transmission surface being dimensioned to be able to bear simultaneously on the head and on the insert clamp.

Mounting device for inserting insulation holders into insulation material, where the mounting device comprises a drive head adapted to drive the insulation holder through a central opening of the head portion of the mounting device, where the central opening is provided with a threaded portion, where the lead pitch of the threaded portion is at least 30 millimetres. The advantage of the invention is that insulation holders can be inserted into insulation material in an easy and cost-effective way. An insulation holder can be driven completely through the central opening since the insulation holder does not have a protruding head. The insulation holder is provided with a thread corresponding to the thread of the central opening, such that the insulation holder is screwed into the insulation material.

The present invention is concerned with improvements to removable fasteners and particularly relates to removable and re-usable fasteners with features that allow them to be gripped and handled positively. The present invention therefore provides a fastening system comprising a fastener and a tool, the tool being suitable for installing and removing the fastener from an aperture in a work-piece, wherein the fastener has a main body and a head at one end, and wherein the head of the fastener and the tool have grip features that allow the fastener to be releasably locked to the tool to prevent separation of the fastener and tool during installation and removal of the fastener. This allows the fastener to be handled positively without fear of the fastener becoming misaligned, or dropping off the tool.

A connector assembly for fastening a rope to a tubular frame includes a pair of sleeves extending inside the tubular frame through a pair of aligned holes. Each sleeve has a flange portion disposed outside the tubular frame and a tubular portion arranged inside the tubular frame. Each sleeve includes a pair of clips biased outwardly of the tubular portion and engaged with an inner surface of the tubular frame. Also, the connecting assembly includes an elongated member coupled with the rope, and extending inside of a first sleeve through a second sleeve. A nut member has a cap portion engaged with the flange portion of the first sleeve, and a hollow cylindrical portion extending inside the first sleeve. The elongated member is disposed, partly, inside and in threaded engagement with the hollow cylindrical portion.
