A hand tool structure includes a handle and a screw head rod. The handle is formed by pouring liquid plastic material into a cave of a mold. The screw head rod comprises a screw head at one end and a plurality of ribs at an opposite end. An end block is formed at the endmost of the ribs. When liquid plastic material is poured into the cave of the mold, the end block will slow down the pouring speed to eliminate any bubbles formed within the cave of the mold. The end block enlarges the contacting area between the screw head rod and the plastic material to enhance the striking force of the hand tool.
