A clamp head including an arched body having upper and lower faces, and opposing unequal length arms. The body further has a through aperture for a bolt or like threaded fastener extending between the upper and lower faces, the through aperture tapering outwardly through the body in the direction of the lower face. The arms comprise a reaction arm having at its distal end a curved reaction face and a clamping arm having at its distal end a curved clamping face. The curved reaction face has a first edge that is proximal to the reaction face and a second edge that is distal to the reaction face, wherein the radius of curvature of the reaction face increases in the direction of the second edge.

Clamp head

A blind fastener adapter for a conventional screw-threaded nut and screw comprises a collar and a segmented ring over the collar, the ring and collar having a tapered interface wherein relative axial movement results in a change of diameter of the ring. The adapter further includes a spring adapted to bias the collar and ring into mutual engagement; the collar and ring include means to prevent substantial relative angular movement thereof. The collar is adapted for engagement by a blind side head of the screw in use, and the ring is adapted for blind side engagement of the perimeter of a hole.

Blind fastener

The present invention provides clamp head comprising an arched body having upper and lower faces, a vertex and opposing unequal length arms. The body is further provided with a through aperture for a bolt or like threaded fastener which extends between the upper and lower faces in the region of the vertex. The aperture in the upper face is oval and tapers outwardly through the body in the direction of the lower face. The arms comprise a reaction arm having at its distal end a reaction face and a clamping arm having at its distal end a clamping face, the reaction and clamping faces being provided with respective formations. The formations of the reaction arm extend in a direction which is substantially transverse to the direction of the formations of the clamping arm.

Beam clamp

Grid clamp for support beam or the like

There is disclosed a clamping device for holding-down a grid-like support member on an underlying flanged support beam, the device being taken in use from the side of the member which is remote from the beam and partly through a space defined between two generally parallel elongate elements of the member, and being manipulatable so as to bring the device into gripping engagement with a flange of the support beam. The device comprises a saddle portion which is shaped so as to be capable of being non-rotatably seated on said elements at said one side of the member, a clamping portion which is engageable with one side of the flange of the support beam which is remote from the grid-like member, and a threaded fastener which interconnects the saddle portion and the clamping portion and which is operable relatively to draw the portions towards each other in order to clamp the grid-like member to the support beam when the saddle portion is seated on the elements and when the clamping portion is in engagement with the flange of the support beam. The clamping portion has a first part which is engageable with said one side of the flange of the support beam and a second part which is generally diametrically opposed to the first part with respect to the axis of the fastener and which has at least two steps each shaped so as to be capable of seating-engagement with one of the elements on a side thereof remote from said one side of the grip-like member. Upon initial installation of the clamping device, the second part of the clamping portion is rotatable by the fastener, as the latter is tightened, until the second part comes into engagement with said one element and one of said steps comes into seating engagement therewith, whereby further tightening of the fastener causes clamping together of the grid-like member and the support beam.

Clamping device

There is disclosed a fixing device for mounting a plate on one side of a flange of a beam, the device comprising a base portion for engagement with an opposite side of the flange, and upstanding portion provided on the base portion, a hole extending through the base and upstanding portions and formed with a screwthread along at least part of its length, and a threaded fastener adapted to be taken through a hole in the plate and into threaded engagement with the hole in the device in order to hold-down the plate onto the flange. The base portion extends eccentrically with respect to the hole in the device, and the hole forms a pivot axis for the device when the threaded fastener is in engagement therewith, whereby the device is pivotable by the threaded fastener between a release position in which the base portion is out of engagement with the opposite side of the flange and a position of engagement with the opposite side of the flange so that, upon tightening of the fastener, the flange is gripped between the plate and the base portion of the fixing device and the plate is held-down onto said one side of the flange.
