What are drift pins primarily used for in machinery?

To create a tighter fit
To align mating parts
To reduce friction
To fasten components permanently

The correct answer is: To align mating parts

Drift pins are primarily used for aligning mating parts in machinery. They are specifically designed to help position two or more components accurately before they are securely fastened together with bolts or other fastening methods. When assembling machinery, it is critical to ensure that parts line up correctly to avoid misalignment that could lead to operational issues or mechanical failure. Drift pins allow a millwright or technician to temporarily hold parts in place as they make any necessary adjustments before permanently securing them. This functionality is essential in maintaining the precision and effectiveness of the mechanical systems being assembled.
