Parallel threaded reinforcement anchorage head provides opportunity for a simpler and efficient anchorage as an alternative to conventional reinforcement anchorage elements such as a miter in the concrete. It is preferably used at the starting and ending points of buildings and subway constructions, particularly in narrow areas where overlapping is not possible. It saves material and labor caused by angulation. This way the area needed to pour concrete and vibration is enlarged, consolidation capacity of the concrete is enhanced, cost of concrete placing is decreased and the quality of the concrete poured on-site is increased.
