Carriage bolts are heavy-duty fasteners typically used in construction or building structures that demand superior strength and durability; the square neck feature ensures accurate alignment while securing materials together. The 3/4-10 size grade signifies its thread count per inch and its compatibility with a variety of surfaces and materials for reliable holding power. This particular 3in length under head, carbon steel carriage bolt also has a square neck providing increased stability when tightened, and allows for more accurate alignment during installation - making it ideal for wood, metal or masonry applications requiring substantial torque resistance. The heavy hexagon head ensures that the nut remains securely in place and does not loosen over time; this type of bolt can be used on wooden beams, decks, or machinery as they deliver high tensile strength against shearing, pulling apart, tension and tensile stressors when fully tightened.
