Abstract

The pressure applicator part is located between a component and a screw head resp. nut. It has an upper contact face (3), and a lower contact face (4) located in the power flux of the part. The part also has an internal profile, which begins in direction of the upper contact face with a radius (6), which is convex to the longitudinal axis (5) of the part, and continues with a straight segment (7) in direction of the lower contact face. If two or more pressure application parts are used, these have different stiffness, and the engaging contact faces are different in outer diameter by max. 20%.
