Standard To Metric Wrench Conversion Chart

Posted on November 08 2019

We all have a mix of wrenches in our tool boxes. Some of us have a lot of SAE, others have a full range of metric and most of us have a balanced mix of both.

Whatever your setup, our wrench conversion chart will tell you the best fitting standard or metric wrench to use for any given bolt.
