Which type of screwdriver has a blunt tip and a 30-degree angle?

The type of screwdriver characterized by a blunt tip and a 30-degree angle is the Phillips screwdriver. This specific design features a cross-shaped tip that allows for a better grip and alignment with the screw head, particularly in applications where torque is required. The angled design helps the screwdriver to fit snugly into the screw slot, reducing the likelihood of slipping or stripping the screw head during use.

The Phillips screwdriver is widely used in various applications, especially in aviation and automotive industries, due to its ability to transmit more torque and its self-centering feature. This means that when used correctly, it can drive screws deeper with less effort compared to other types of screwdrivers.

Other options, while useful in different contexts, do not share the specific characteristics of the Phillips screwdriver. For example, flathead screwdrivers have a straight, flat blade designed for traditional slotted screws, while Torx and hex screwdrivers are designed for specific types of screw heads that require a star or hexagonal shape. Each of these alternatives has its unique applications but does not include the blunt tip and 30-degree angle that define the Phillips screwdriver.
