What to know before buying

Listing details to confirm

Listing details are contradictory or inconsistent: the title identifies a 7.5 Amp 1/2-inch impact wrench, while separate detail fields call the head style “Box End” and state torque as “204 kN,” unlike the feature and description claims of 450 ft.-lbs. Treat the latter performance figures as listing claims and confirm the intended specification before purchase.
