Q: Will this work with my 1-inch impact wrench? A: Yes, the integrated ball detent recess creates a secure connection with all 1-inch drive impact wrenches, breaker bars, and torque multipliers. The socket handles air guns delivering 1,200+ ft-lbs of torque without slipping or detaching, compatible with pneumatic, electric, and manual drive tools.

Q: How deep is this socket compared to standard versions? A: Deep impact sockets typically measure 2-3 times longer than standard sockets to accommodate extended wheel studs and recessed lug nuts. This extra length prevents binding when accessing fasteners buried behind hubcaps, wheel covers, or thick mounting flanges common on commercial vehicles.
