Spray the hardware with a multi-purpose lubricant to loosen it a little. Choose the right size socket for your bolt. Fit it over the bolt and use a wrench or breaker bar with some elbow grease to gradually loosen the nut.
For rusty or stripped bolts
These ones you may need a bolt remover. Bolt removers have textured interiors to help grip nuts or bolts with worn out threads or that have become misshapen from rust. Choose the right size bolt remover for your bolt and attach it to a socket wrench. Apply pressure until the bolt gives.
For extra torque
If it’s power you’re lacking, an impact wrench will help you get the job done. These power tools make quick work of high-torque projects and tough fastening applications. Just make sure to use impact sockets or bolt removers with your impact wrench.
