A 5x250mm line color slotted screwdriver is a flat-head screwdriver with a long, slender shaft (250mm) and a 5mm wide tip, designed for reaching deep or narrow spaces. The "line color" feature usually indicates the handle’s color coding, which helps quickly identify the type or size of the tool in a set. This screwdriver is ideal for tightening or loosening slotted screws, commonly used in electrical, mechanical, and general maintenance tasks. Its ergonomic design provides comfort and grip for precise control.
