摘要:
A threaded joint arrangement with visual and tactile indication of correct tightening force, the threaded joint arrangement comprising a threaded fastener (20) having a fastener shaft (21) and a fastener head (22), a biasing member (30), a first object (40) provided with a cavity (41) recessed in a reference surface (42) of the first object (40), wherein the cavity (41) has a bottom surface (43) provided with a through hole (44), and a second object (50) provided with a threaded hole (51). The through hole (44) is aligned with the threaded hole (51) and the threaded fastener (20) is arranged such that the fastener shaft (21) extends through the through hole (44) and is in threaded engagement with the threaded hole (51) of the second object (50). The biasing member (30) is arranged in the cavity (41) between the fastener head (22) and the bottom surface (43) of the cavity (41) and is configured to be compressed between the fastener head (22) and the bottom surface (43) of the cavity (41) in response to rotation of the threaded fastener (20) in a tightening direction. An alignment surface (11) of the threaded joint arrangement is movable by rotation of the threaded fastener (20) between a first position in which the alignment surface (11) is positioned outside the cavity (41) and a second position in which the alignment surface (11) is flush with the reference surface (42), wherein the biasing member (30) has a spring constant configured such that a tightening force of a predetermined level is obtained when the alignment surface (11) is in the second position.
