Metric to Imperial Conversion Table

AccuGroup understands the importance of finding high-precision components which are an exact match for their intended application. For many components such as Dowel Pins or Washers, an imperial or metric equivalent can often be the ideal solution. AccuGroup's imperial conversion table will help in finding suitable components for your application.

Please note: When interchanging metric and imperial threaded fasteners, it is important to take into account the difference between metric and imperial thread pitches. More information can be found in our Unified Thread Standard Conversion Table.
