How to install a square neck carriage bolt correctly?

To install a square neck carriage bolt, drill a hole matching the bolt diameter and a square hole for the neck. Insert the bolt so the square neck seats firmly, preventing rotation. Tighten the nut from the opposite side with a wrench. Use a washer under the nut to distribute load and prevent galling.
