How to use
Select the Hazet 828-4 when a dedicated metric size 4 hex driver is required. Insert the hex tip fully into the head of the M4 screw or bolt to ensure maximum contact between tool and fastener. Apply steady turning force with controlled wrist motion; avoid excessive side loading that could damage the screw head. For initial loosening, turn counterclockwise; for tightening, turn clockwise and monitor torque applied to prevent over-tightening. Clean the hex tip and fastener recess of debris before use to maintain fit quality.
Usage recommendations
Use the tool only on matching metric 4 hex fasteners. Inspect the tip for wear before critical tasks and replace if the hex profile is rounded. For high-torque requirements, consider using a longer or ratcheting hex tool rated for increased torque to avoid stressing the screwdriver handle.
