Frequently Asked Questions

Q: How does this compare to buying separate 19mm and 21mm impact sockets? A: The flip design saves drawer space and eliminates the need to hunt for different sockets during jobs. While slightly heavier than individual sockets, it's more efficient for mixed-size work and reduces tool clutter in your workspace. The convenience factor is especially valuable during multi-vehicle service days.

Q: Will this socket work with my 1/2" cordless impact wrench? A: Yes, this socket works with all standard 1/2" drive impact wrenches, both pneumatic and cordless. It's designed to handle the torque output of professional impact tools while maintaining secure attachment to the anvil. The chromoly steel construction ensures it won't crack or deform under high torque loads from modern cordless impacts.

Q: What makes the 6-point design better than 12-point sockets? A: 6-point sockets contact lug nuts at the flat surfaces rather than the corners, distributing force more evenly and reducing the risk of rounding. This is especially important with aluminum wheels where lug nuts are softer and more prone to damage. The broader contact area also provides better torque transfer and reduces slippage during high-force applications.

Q: How deep are the socket wells on this flip socket? A: This is a deep-well impact socket designed to clear extended lug studs and provide better engagement on recessed applications. The deep design accommodates most passenger vehicle and light truck lug configurations without bottoming out on the stud. This extra length is particularly useful when working with aftermarket wheels that may have longer studs or spacers.
