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.

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.

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.
