Which screwdriver has a cross-shaped blade?

• A. Standard screwdriver
• B. Phillips screwdriver
• C. Allen wrench
• D. Offset screwdriver

Answer: (B)

The Phillips screwdriver features a cross-shaped blade specifically designed to fit into the cross-shaped recesses of Phillips screws. This design allows for better grip and torque compared to other screw types. The cross shape enables the screwdriver to align with the screw's recess and minimize slipping or cam-out, which is when the screwdriver loses grip and can strip the screw or damage the surrounding material. This is particularly useful in applications where a strong connection is required, and it's common in a variety of settings, including both household and industrial tasks. In contrast, the standard screwdriver has a flat blade used for slotted screws, while the Allen wrench is specifically designed for hexagonal socket screws. An offset screwdriver is designed for accessing screws in tight spaces but does not have the cross-shaped blade characteristic of the Phillips screwdriver.
