## How can you tell if a bolt is metric or standard?

Telling the difference between a metric and imperial bolt is easy. If the bolt has lines on the head its standard or imperial. If the bolt has numbers on the head then its metric. These markings indicate how strong the bolt is they call this tensile strength.
