What to know before buying
Listing details to confirm
Listing details are contradictory or inconsistent: the title says bare tool while an included-components field lists a tool bag, and clutch descriptions vary between 20+1+1 and 24+1+1. Confirm the selected listing’s package and clutch configuration. The stated 1062 in-lb torque is a manufacturer claim, not an independently verified measurement.
