What is the impact of not properly tapping a hole before inserting a bolt?

Not properly tapping a hole before inserting a bolt can result in a misalignment or improper fit of the bolt within the hole. Tapping is the process of creating internal threads in the hole that match the external threads of the bolt. If this step is skipped or executed poorly, the bolt may not align correctly, making it difficult to insert and secure properly. This misfit can lead to insufficient mechanical strength when the bolt is tightened, which can compromise the integrity of the assembly. Proper tapping ensures that the correct thread pattern and depth are established for a secure fit, facilitating effective load distribution and enhancing the overall strength of the connection.
