No, these extension bars are not designed for use with impact drivers. Using them with an impact driver may cause damage.
The extension bars are made from steel and have a polished chrome finish.
The set includes extension bars of 75mm (3"), 150mm (6"), and 225mm (9") in length.
Wipe the extension bars with a clean cloth after each use. You can use a bit of solvent to remove stubborn grease or grime. Store the bars in a dry place to prevent corrosion.
These extension bars have a 1/2" drive.
The polished chrome finish provides durability, corrosion resistance, and makes cleaning easier.
Use a socket removal tool or apply penetrating oil and gently tap the bar to dislodge it.
Reduce the torque applied. Consider using a shorter extension bar or a different tool if necessary. Ensure the socket is properly seated on the fastener.
