💡 How do I pick between 1/4, 3/8, and 1/2 inch drive socket sets?
Drive size comes down to the fastener size and how much torque the job needs.

• 1/4 inch drive sets work best on small bolts and tight engine bay spots
• 3/8 inch drive sets handle most everyday auto and home repair
• 1/2 inch drive sets are built for big bolts and high torque
