Wind Turbine Foundation Anchors

Williams Form Engineering pioneered the heavy-duty thread forms present on the Grade 75 and 150 KSI anchor bolts three decades ago for use in the civil construction industry. The anchor bolts gained popularity due to the rugged nature of the thread form and concentric thread design. The wide thread pitch allows for fast hex nut engagement while still allowing precise adjustments when necessary. These factors contributed to designer acceptance of the Williams Grade 75 and 150 KSI threaded bars in the late 1990s as renewable energy started to gain wide range acceptance. Today each wind tower supported by a Williams foundation anchor bolt can be relied upon to perform flawlessly throughout the life of the turbine.
