Screw thread shear
WebbThe threads shear and the screw becomes a pin basically. The screw shaft snaps. So you use the screw material to get your elastic modulus for tension and for shear. Then you calculate the total area the force would be applied against (the screw shaft area for tension or the combine area of thread contact for shear).

Webb1 juli 2016 · For bolted joints without a preload shear, stress is calculated like bearing stress: force over area. Like bearing stress, it is also an average stress and the maximum shear will be higher. If a ... WebbThe tighter threads will ensure that the screw can be more tightly clamped. 3. The Quality of the Screw. You might also want to think about the quality of the screws that are using. The stronger the screw, the more weight it will be able to hold. On the other hand, a weaker screw might buckle under the pressure, causing them to shear off.
