Before ordering
Match impact-rated sockets to the quarter-inch drive and actual fastener head. M8 identifies a bolt designation, not an 8 mm socket opening. Use a torque wrench for prescribed final tightening rather than relying on the impact's performance range.
Product questions and answers
Does M8 mean an 8 mm socket is required?
No. M8 refers to the bolt designation. Determine the head size separately and choose the corresponding socket opening.
Can half-inch drive sockets fit directly?
No. This model has a 1/4-inch square drive. Select the correct drive interface and impact-rated accessories.
Is 29.5 ft-lb a selectable calibrated setting?
No. It is the upper end of the listed forward range, not a calibrated torque adjustment. Verify final torque separately.
