What differentiates a close tolerance bolt from a general purpose bolt?

Close tolerance bolts are specifically designed and manufactured to meet precise dimensional and geometrical specifications, ensuring a higher degree of accuracy in their dimensions compared to general purpose bolts. This precision is critical in applications that require tight fits and reduced play between components, helping to maintain the integrity and performance of assemblies in aerospace environments.

The tighter tolerances in these bolts help to minimize gaps, reduce the likelihood of movement, and enhance overall mechanical stability, which is essential for safety and functionality in aviation applications. This level of manufacturing quality is why close tolerance bolts are used in more demanding situations than general purpose bolts, which do not require such stringent specifications.
