What is the torque limit? Can I use it on tight bolts?

The Offset Extension 2.0 is rated to 53 ft-lb (72 Nm). It’s made for spark plugs and everyday bolts, not for breaking loose seized or high-torque fasteners. For anything tighter, crack it loose with a breaker bar first, then use the extension to spin it out. Going over the limit can damage the chain inside.
