Engineering Design Manual - Helical Anchors, Inc.The earliest recorded uses of helical anchors were by an Irish engineer, Alexander. Mitchell, who used them to support a lighthouse. Screw piles were not popular because the force of many men was required to produce the necessary torque. Through the years screw piles were improved, and increased, especially when.helical screw calculator,Calculate the flat form of tapered helical screw flight - CADTutorDec 22, 2017 .
