Abstract: There is provided a torque specifying nut which is suitable for being applied to a wind-fastening strap metal piece, capable of clamping only up to a specified clamping torque and capable of confirming whether clamping has been finished or not at a glance.

Abstract: A fastening fixture of a simple and compact structure comprising: a fixture body; a screw having a stem portion inserted into the fixture body; and a fastening nut screwed on the stem portion of the screw. In order that a temporarily fixed state may be established by inserting the fastening nut into an entrance channel or hole into the fastening nut with the fixture body being griped and by turning the fixture body by 90 degrees, the fixture body is provided with a depending member in parallel with the stem portion of the screw, and the fastening nut is provided at its longer side edge portion with a guide portion which is regulated in its turn but allowed to move only in parallel with the stem portion of the screw by fitting on or confronting the depending member. Therefore, the fastening fixture can effect the temporary fixing and the fastening fixing simply independently of the depth or inner width of the channel or hole.

Abstract: It is an object to provide a fixture which enables ready, accurate and positive preliminary mounting of an electric line part in completely one operation without the need for any screwing operation, regardless of a change in the width and height of the channel flanges of a channel rail and also, enables ready and positive permanent securement of the electric line part, and which allows an operator to extremely easily, positively and efficiently carry out this type of operation without the need for any skill.A means for clamping electric line parts according to the present invention comprises a fixture body 1 having a part attached to a channel rail 4, a bolt 2, and a clamp 3 threadedly engaged with the bolt 2. The clamp 3 includes a central nut 3B, pivot pins 8, 8 mounted to the nut 3B, a pair of right and left clamping elements 3A, 3A pivotable about the horizontal pivot pins 8, 8, and a protrusion 8a extending outwardly from one side of the nut 3B.

Abstract: A clamping device for clamping a conduit to a channel rail, comprising a main unit with a retainer section of which the shape fits the sectional form of the conduit, a screw member and a buckle. Just pushing the screw member axially causes abutments of the buckle to be engaged on the channel rail and thus the conduit is fixed to the channel rail at least provisionally. The abutments of the buckle are made to engage the channel rail just when the screw member is pushed axially by holding the buckle in a predetermined direction in the main body until the screw member is pushed axially, rotating the buckle when the buckle is released from the held state so that the abutments are positioned under the lower ends of a pair of inlet-opening walls defining together an inlet opening of the channel rail, and drawing the buckle in the direction of the head of the screw member while the abutments are kept positioned under the lower ends of the pair of walls.
