How to install a square neck carriage bolt?

To install a square neck carriage bolt, drill a hole matching the bolt diameter. Insert the bolt through the hole so the square neck seats into the material, preventing rotation. Tighten the nut from the opposite side with a wrench. For best results, use a washer under the nut to distribute load and prevent galling.
