ABSTRACT OF THE DISCLOSURE Torque limiting clamping means comprises a cylindrical unthreaded screw-thread engaging clamping member of elastomeric material screwed on a rigid screw threaded member at an interference fit. The interference fit, the pitch and dimensions of the screw thread, and the physical characteristics of the elastomeric material are preselected to enable deformation of the elastomeric material resiliently within its elastic limit into the thread groove of the rigid member to accommodate the interference fit and to cause screw-induced relative axial movement of the members to a limit of axial travel. Relative rotation of the two members also produces screw-induced torque forces. The unthreaded elastomeric member has an abutment means which engages a clamped part. The resistance forces produced by the clamping in combination with the torque forces provide a limit to the relative axial travel at such limit. The forces achieved between the clamping members and the clamped part at such limit are sufficient to maintain the clamping relationship.
