💡 Should you buy metric or SAE sockets?
Most folks need both, since cars and gear use a mix of fasteners.

• Metric sockets fit most import and late-model domestic vehicles
• SAE sockets cover older American cars, trucks, and equipment
• Using the wrong system can strip or round off a bolt head
• A mix of both sizes in your toolbox saves you headaches
