Sjabloon:Imperial

WARNING: Imperial tools have slightly different sizes than Metric ones.

Using the wrong one will often damage the bolt, nut or whatever you are working on. See this list for all the imperial tools we have.

Try not to mix them with our metric tools -- to make sure your fellow maker does not ruin their work.
Be especially careful with the close friends, such as sizes like 5/8inch and 16mm;
although the difference is 0.13mm - you will ruin (or usually just crack) a collet or similar..
