### Transtar Part Numbering Guide

The Part Numbering Guide is a reference document that explains our part numbering system of using a variable prefix, base number and suffix that when broken down will tell you the application, type of part, and additional information such as type of material. Since the logic of this system is applied across the board, it is very easy to learn once you understand how it is set up.
