Which statement about nuts is true?

The correct answer affirms that nuts have greater or equal strength compared to their matching bolts, which is an important aspect of their function in fastening applications. The strength of a nut is crucial because it is responsible for securing the joint by holding the bolt in place under various loads and stresses. In most cases, nuts are designed to match or exceed the strength specifications of their corresponding bolts. This ensures that when a bolted joint is subjected to forces, the nut will reliably hold the bolt without deforming or breaking, thereby maintaining the integrity of the assembly.

Furthermore, the design and materials used in nuts often allow them to provide robust resistance to shear and tension, which are essential for maintaining tight, secure fastening in mechanical structures. This characteristic reinforces the overall strength of the bolted connection, as the weakest component often determines the performance of the joint.

Understanding this relationship between bolts and nuts helps manufacturers and engineers choose the correct fasteners for various applications, ensuring safety and functionality in their designs.
