A threaded joint arrangement with visual and tactile indication of correct tightening force, includes a threaded fastener having a fastener shaft and a fastener head, a biasing member, a first object provided with a cavity in a reference surface with a bottom surface provided with a through hole, and a second object with a threaded hole. The through hole is aligned with the threaded hole and the fastener shaft extends through the through hole and is in threaded engagement with the threaded hole. The biasing member is arranged in the cavity between the fastener head and the bottom surface and is compressed between the fastener head and the bottom surface in response to rotation of the threaded fastener. An alignment surface is movable by rotation of the threaded fastener between a first position outside the cavity, a second position flush with the reference surface and a third position inside cavity.
