PURPOSE: A finishing head of pile to be inserted is provided to accomplish convenience and easy assembly of the same without centered stress by puncturing a bolt hole on the head for inserting the pile head and filling the bolt into the hole. CONSTITUTION: The head of pile is for preventing over-centering of perforation shear stress at load transfer between a basis and a steel pile and for preventing a base concrete(9) from inflowing into the steel pile(8) by boring a bolt hole on the steel pile corresponding to another bolt hole of a cylindrical wall(2); and coupling a bolt(6) into the hole. The head can comprise a flange(5) formed of hollowed circular plate at upper end of the cylindrical wall by welding the plate and have three holes at lower portion and at least three bolt holes at upper portion of the cylindrical wall.
