Wellhead equipment support
A wellhead assembly is described for supporting equipment in a well, comprising: a suspension nut having a threaded outer surface; a wellhead member having an inner threaded surface adapted to mesh with the threaded outer surface of the suspension nut; the suspension nut having a projection extending axially from its threaded outer surface and having an inner surface adapted to support equipment in the well; at least a portion of the inner surface for supporting the equipment facing both inwardly and upwardly such that force exerted by the weight of the equipment against the inner surface is transformed at least in part to a radially outwardly directed force; the projecting having an outer surface sized such that the outer surface is spaced from an inner surface of the wellhead member in the absence of force exerted against the inner surface of the projection such that the projection is deflected outwardly by the force exerted by the weight of the equipment against the inner surface.
