Which screwdriver is specifically used for precision assembly of small parts?

The jewelers screwdriver is designed specifically for precision assembly of small parts, making it the ideal tool for tasks that require delicacy and careful handling. Its smaller size allows it to reach tight spaces and work with tiny screws commonly found in watches, eyeglasses, and other delicate devices. The precision tip provides a better fit for small screws, which reduces the risk of stripping the screw head and damaging the component being worked on.

In contrast, the flathead screwdriver, while useful for larger, slotted screws, is not designed for the intricate work that small assemblies require. The Phillips screwdriver is more suited for screws that have a cruciform shape but lacks the finesse necessary for very small components. The torque screwdriver is primarily used to apply a specific amount of torque to a fastener and is not designed for precision work on tiny screws, which would typically require a more delicate touch. Therefore, the jewelers screwdriver is the most appropriate choice for precision tasks involving small parts.
