定座金。 A spring washer with a cross section that always keeps the center radius of contact with the bolt or nut seating surface constant, and the relationship between the tightening torque and the axial force generated by the bolt can be made proportional and the variation can be reduced. A tightening axial force stabilizing washer that enables tightening with a target axial force through torque management, and prevents the tightening axial force from decreasing due to spring reaction force.
