💡 How do you pick the right socket drive size for a job?
Drive size should match the fastener size and how much muscle the job needs.

• 1/4 inch drive sockets are great for small bolts and tight spaces
• 3/8 inch drive is the everyday pick for most car repair
• 1/2 inch drive handles lug nuts, suspension, and big bolts
• 3/4 inch and 1 inch drive are for heavy trucks and equipment
