THE SLEEVE BEARS MEANS FOR ATTACHMENT TO ONE OF THE SKIN SHEETS OF THE HONEYCOMB BODY, AND THE SPACER HAS AN ABUTMENT SURFACE ADAPTED TO BE THREADED DOWN INTO CONTACT WITH THE OTHER OF SAID SKIN SHEETS SO AS TO CLAMP SAID OTHER SHEET BETWEEN ITSELF AND A WORKPIECE WHICH IS TO BE ATTACHED TO THE BODY. THE FASTENER TRANSFERS BOTH SHEAR AND TENSILE LOADS TO THE HONEYCOMB BODY, AND THE THREADED JOINDER OF THE SLEEVE AND SPACER MAKES THE GRIP RANGE DELICATELY ADJUSTABLE, AND PROTECTS THE HONEYCOMB BODY FROM CRUSHING WHILE THE FASTENER IS BEING SET.
