When installing nuts, what is critical to check for in the bolts?

When installing nuts, it is crucial to check that the bolts are the same diameters and have the same number of threads per inch. This ensures proper fitment and function, as the nut must match the bolt's specifications to secure components effectively. If a bolt has a different diameter or thread count than the nut, it can lead to improper fastening, potentially causing joint failure or damage during operation.

Stringent adherence to specifications such as diameter and threads per inch guarantees that the load distribution is even and prevents issues related to potential stripping or loosening due to mismatched sizes. Using mismatched bolts and nuts could lead to dangerous failures in critical applications like aircraft structures, making this check essential during installation.
