The round head gives a clean exposed side, while the square neck helps stop the bolt from rotating when the nut is tightened from the opposite side.<\/p>\n      <p>For export sourcing, the key is to define the installation condition. Wood, soft steel, slotted holes, and pre-punched square holes do not behave the same. Buyers should confirm head size, square neck dimensions, thread length, coating thickness, and whether bolts will be shipped alone or packed with matching <a href=\"https:\/\/xzfastener.com\/fastener-type\/nuts\/\">industrial nuts<\/a> and <a href=\"https:\/\/xzfastener.com\/fastener-type\/washers\/\">flat washers<\/a>.<\/p>\n      <div class=\"xz-note\">A carriage bolt that looks correct in a photo may still fail the assembly check if the square neck does not seat properly.
