💡 How do I know if I need a metric or SAE socket?
Match the socket to the fastener, since metric and SAE sizes don't swap well.

• Most newer cars and imports use metric bolts measured in millimeters
• Older American vehicles and a lot of equipment use SAE sizes in inches
• Using the wrong system can round off bolt heads fast
