Applications:

The are designed to be inserted through the hole of a bolt or nut and then bent into different shapes that lock it in place and prevent the fastener from loosening.

Automotive industry

Marine and aerospace

Industrial automation and manufacturing

Engineering

Are cotter pins re-useable?

As a rule, it is important not to re-use the split pin because the bending of the pin that locks it into place weakens the structure of it when it is re-bent and straightened to be re-used, which could lead to the pin failing.
