How To Use A Carriage Bolts

To use a carriage bolt, you may need some additional tools. Some of these include:

  • First, drill a hole in the material and make sure it is large enough for the size of your selected carriage bolt
  • Next, place the carriage bolt in the hole. A soft hammer can be used to place it gently in the hole if you notice that it is a tight fit.
  • Finally, if you choose to use a washer and nut, place the washer and nut on the carriage bolt and tighten them.

During your carriage bolt installation, using a washer with your nut is essential. A washer will prevent damage done by putting the nut in place. If you need to remove a carriage bolt, all you need to do is twist the nut while keeping your carriage bolt in place. This can be done with a combination open and box wrench.
