Q: Why use radius-corner geometry?
A: This design applies force to the flat sides of fasteners rather than the corners, reducing rounding and preserving both tool and fastener under heavy impact torque.

Q: Is this socket deep-well or standard-length?
A: It is semi-deep, meaning it offers extra reach for recessed fasteners while avoiding the flexibility issues of longer sockets.

Q: Will this fit my 3/8-inch impact wrench?
A: Yes, it is made from chrome molybdenum alloy steel and built specifically for use with 3/8-inch drive impact tools and 17 mm hex fasteners.
