<p>#CMT# #/CMT# The fastener (50) has an assembly of a central rod (53) and half clamps (56) axially displaced along a spacer (58), in the form of a flat plate, by rotating a nut (54) on a threaded end (53a) of the rod between rest and active positions. Hooking tips (57) of the clamps are radially moved closer to be engaged in orifices of elements in the rest position. The assembly presents, in section, in form of a circle in the rest position, where a diameter of the circle is identical to an internal diameter of the orifices with a minimum clearance for longitudinal sliding of the assembly in the orifices. #CMT#USE : #/CMT# Anchoring screw fastener for being introduced in coaxial orifices of two elements i.e. wings, of an aircraft i.e. airplane, for temporary fixation of a drilling grid on the elements in a fuselage of the aircraft. #CMT#ADVANTAGE : #/CMT# The assembly presents, in section, in form of a circle in the rest position, where the diameter of the circle is identical to the internal diameter of the orifices with the minimum clearance for longitudinal sliding of the assembly in the orifices, thus facilitating precise positioning of the grid on the wings without damaging the orifices of the elements. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of an anchoring screw fastener. 50 : Anchoring screw fastener 51 : Hollow body 53 : Central rod 53a : Threaded end 54 : Nut 56 : Half clamps 57 : Hooking tips 58 : Spacer.</p> |
