💡 Can you use a chrome socket on an impact wrench?
It's not a good idea, since chrome sockets aren't made for impact hammering.

• Chrome sockets are hard and can crack or shatter under impact force
• Impact sockets use tougher steel and thicker walls to handle the hits
• Save chrome sockets for hand ratchets, breaker bars, and torque wrenches
