Q: Are both SAE and metric hex sizes included?
A: Yes. The set includes 10 SAE sizes (1/4 to 3/4 inch) plus 10 metric sizes (6 mm to 19 mm).

Q: Why are these drivers 6 inches long?
A: The extended 6-inch length helps reach fasteners located deep within assemblies or recessed brackets where standard short bits cannot reach.

Q: Can these hex drivers handle impact tool torque?
A: Yes. They are forged from Cr-Mo alloy steel and designed specifically for impact use; using them in non-impact or under-rated tools may reduce tool life.
