WebShear strengthis a term used in soil mechanicsto describe the magnitude of the shear stressthat a soil can sustain. The shear resistance of soil is a result of friction and interlocking of particles, and possibly cementation or bonding of particle contacts. WebShear Strength of a Threaded Fastener As a general rule, it can be said that the shear strengths of carbon steel fasteners are roughly 60% of the minimum tensile strengths that are provided for them. An SAE grade 5 hex cap screw, for instance, has a 120,000 psi minimum tensile strength requirement.
