  • Frequently Asked Questions
    Are GEARWRENCH impact adapters warrantied?
    Yes, a full lifetime warranty. See: https://www.gearwrench.com/warranty or contact the retail location where you made the purchase.
    Is this socket designed to withstand high-torque, heavy-use environments?
    Yes. Rigorous impact cycle testing and design iterations have resulted in a most durable tool.
    Why is the socket spring loaded?
    The design incorporates two common hex sizes in the same end, reducing the need to change over tools. Because it is spring loaded, the inner socket automatically moves when engaging on the larger size.
