Can cotter pins be reused?

Yes, multiple times
No, they are a one-time use
Only if they are inspected
Only under specific conditions

The correct answer is: No, they are a one-time use

Cotter pins are designed for a single use, as they can lose their strength and structural integrity after being bent and removed. When a cotter pin is installed and then taken out, the bending process can cause fatigue, cracking, or deformation, meaning that it may not hold fastenings securely upon reinstallation. This is why the practice in millwrighting and mechanical work is to replace cotter pins after they have been used once, ensuring a reliable and safe assembly. In the context of the other choices, suggesting that they can be reused with inspection or under specific conditions could lead to safety risks if the pin has suffered from damage during its initial use. Safety protocols in machinery and mechanical applications prioritize reliability and integrity, which is why cotter pins are classified as one-time use components.
