True or False: Bolts in a flange must run through the nut completely to ensure full engagement.

The statement that bolts in a flange must run through the nut completely to ensure full engagement is indeed false. While it's crucial for bolts to have adequate engagement for strength and to avoid failure, full engagement is not strictly required in all applications.

In many instances, the design of the flange and the application it is used for may allow for partial thread engagement without compromising the integrity of the connection. As long as the bolts are adequately tightened within their specified torque range and the materials and design are appropriate for the load conditions, complete thread engagement may not be necessary.

However, it is essential to ensure that there is enough threaded length engaged to withstand the forces acting on the joint. This consideration varies significantly based on the specific application and assembly requirements. Different materials and sizes of flanges may have specific protocols, but the overall guideline is that while full engagement is generally ideal, it is not an absolute requirement in every case.
