How to install a square neck carriage bolt?

To install a square neck carriage bolt, insert the square neck into a matching square hole in the material to prevent spinning. Tighten the nut from the opposite side with a wrench. For best results, use a washer under the nut to distribute load and avoid over-torquing, which can strip the threads.
