Bolt thread shear stress
WebAug 2, 2024 · In case your bolt is quite strong (let's say, made of 180 ksi alloy steel) relatively to the plate material, it is indeed important to verify that the thread would not shear, or pulled out. This pull-out force calculated as follows: the shear strength of the material X pi X thread diameter x thread depth x thread efficiency. Webnominal bolt stress area according ISO 724 Tensile Stress Tensile stress can be calculated as σ = F / A (3) where σ = tensile stress (psi, N/m2 (Pa)) Example - Bolt Stretching - Imperial Units stud diameter : 7/8 inches thread pitch : 9 Young's Modulus steel : 30 106 psi designed bolt load : 10000 lb effective length : 5 inches

WebOct 3, 2024 · Generally, the minimum thread engagement length for a joint is determined such that the full tensile strength of the bolt is utilized prior to shearing of nut threads. In other words, it is expected that the shear failure occurs in the fastener part, often externally threaded, and the failure occurs only after utilizing full tensile strength.
