To commemorate 200 years of independence from Spain, Mexico announced in 2009 plans to build a 341-foot monument. Due to the height, corrosion concerns, and wind shear factors, the project engineers determined 17-4 ph to be the most suitable material forthis project. After international competition, Atlanta Rod was awarded the bid to manufacture over 34,000 specialty 17-4 ph stainless bolts, nuts, and washers from M16 through M39. All tooling for this project was produced in-house by our tool and die team. These bolts and nuts were precision forged to structural metric tolerances of within .004”. In total, Atlanta Rod manufactured over 50,000 pounds of finished product in four weeks. This special monument will forever change the Mexico City skyline.
