Are All Bike Allen Keys Metric?
The vast majority of bike allen keys are metric, with only a few exceptions.

While a few companies do make standard allen keys, they are not as common and are generally not as well-suited for use on bikes.

What Is The Difference Between Metric And Non-Metric Allen Keys?
The main difference between metric and non-metric allen keys is their size. Metric allen keys are typically smaller than non-metric allen keys, which means they can be used in tighter spaces and are less likely to slip out of the bolt head. Metric allen keys are also generally more precise, as they are less likely to round off the corners of the bolt head. Another difference between metric and non-metric allen keys is the shape of the tip. Metric allen keys have a more pointed tip, while non-metric allen keys have a more rounded tip. This difference is due to the fact that metric allen keys are designed to fit into the smaller metric-sized bolt heads, while non-metric allen keys are designed to fit into the larger non-metric-sized bolt heads. Overall, metric allen keys are the better choice for most applications. They are more precise, easier to use in tight spaces, and less likely to slip out of the bolt head. If you are working with non-metric-sized bolts, however, you will need to use a non-metric allen key.
