WebbThe main bolt loosening reasons: Spontaneous bolt loosening - shock, vibration, dynamic load. Slackening - settlement, creep, relaxation. To prevent spontaneous bolt loosening, the slip between the joined parts needs to be eliminated or at least reduced to below critical levels. This can be achieved by either increasing the axial tension ... WebbWikipedia

Second, the nut is sliding, indicating that the friction force will be equal to the normal force times the kinetic coefficient of friction. Ff = μk ∗ FN

Webb28 feb. 2024 · Self-tapping wood screws are important fasteners in timber construction. A characteristic of these screws is their high axial load-bearing capacity, which also depends on their withdrawal capacity. This is used for structural design and is thus an important optimization parameter for wood screws.
