Built to Hold: The Enduring Strength of Square Head Bolts
There’s a reason square head bolts are still forged, installed, and trusted after centuries of use—they work hard, hold strong, and carry a visual weight that round heads just can’t match. At Old West Iron, we don’t just carry them—we honor them.
A Legacy of Strength
Square head bolts date back to the early days of blacksmithing, long before standardization and modern machine threading. They were used in timber frame barns, railroad trestles, mining equipment, and iron bridges—anywhere failure wasn't an option. Their bold, geometric heads offered more surface grip for hand tools of the era, making them ideal for field repairs in rugged conditions.
And while most hardware has gone sleek and soulless, these bolts still stand as a symbol of strength—literal and visual. They carry a historical presence that feels right at home in restoration projects, period architecture, and rustic builds where detail matters.
