Updated Part Numbers

Out with the old, in with the new!

Over the last few years, Chapman has been updating our original part numbering system to make things a lot simpler and straightforward. If you're one of our OG customers, you might notice when ordering new/replacement parts that they are stamped just a little bit differently. We changed our Phillips, SAE hex, and Metric hex part numbers to match their actual size.

Use the charts below to know what to look for when searching the website or when your new parts come in the mail!
