How to Join Wood with Carriage Bolts

When joining pieces of wood together using a carriage bolt, the square head on the bolt can become stripped in the hole, making them hard to tighten. To solve this problem, insert a few finishing nails in the hole beside the bolt before hammering the bolt into place. The nails will fill the gaps between the hole and bolt to keep it from spinning.


  1. Thanks to your web site I was able to learn the difference between carriage bolts and lag screws and decide which was right for my job. I tried 3 other web sites first, unsuccessfully.

    Thank you for have such thorough information.

  2. Hi Linda, Glad you liked the tip on using carriage bolts. I use them all the time. In fact, I recently built a picnic table and used carriage bolts to join the legs to the table’s frame. Thanks for writing, and good luck!–Joe T.

  3. Loved the info. Would the carriage bolts be best to use for a dinning room table when putting the legs on? And especially if you move around a lot to take apart? Thank you in advance
