How to Loosen a Bolt

Bolts are threaded fasteners that are used in conjunction with a nut to secure two or more materials. There are two size classes of nuts and bolts: metric and U.S. standard. Metric hardware is now standard in all countries except the United States. New products made in the U.S. will usually use metric hardware, but some older products, especially cars, will use standard sizes. It is important to know whether the bolt and nut are metric or standard, and to use the proper tool, so as not to damage them.

Instructions

1




Determine the correct wrench sizes needed for the bolt and nut. The head size of the bolt will usually be larger than that of the nut.

2




Place the wrenches or socket on the bolt head and the nut. Hold the bolt head still and turn the nut counter-clockwise.

3




Finish removing the nut by hand once it is loose enough. This will reduce the chance of dropping it as it comes free of the bolt post.
