My next question is are they made in American and Metric sizes ? If so I assume Germans used Metric. Anyone know the answer to this one ??
Torx drivers come in standard sizes, T10, T15, T20, etc. The bigger the number, the larger the driver. The bolt threads may be SAE or Metric, but the holes for the driver are the same. Hope that makes sense.
