How Much Load Can a Bolt and Nut Withstand? Strength and Calculation Methods From industrial design to civil engineering, bolts and nuts play a critical role in ensuring the safety and durability of structures. The load-carrying capacity of a bolt and nut depends on the material type, dimensions, and the design of the joint. In this article, we’ll explore how to calculate the load-carrying capacities of bolts and nuts and the factors to consider during the process. Load-Carrying Capacities of Bolts and Nuts The load-carrying capacities of bolts and nuts are determined by parameters such as tensile strength , shear strength , and tightening torque . These parameters depend on the bolt’s dimensions, material, and manufacturing quality.     1. Tensile Strength Tensile strength refers to a bolt's resistance to axial pulling forces. It is calculated as the product of the bolt's cross-sectional area and the material’s ultimate tensile strength (UTS). Tensile strength formula:...
