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

The type of screwdriver that is characterized by a blunt tip and a 30-degree angle is the Phillips screwdriver. It is specifically designed with a cross-shaped tip that allows it to grip and fit into the corresponding cross-shaped screws, providing a robust connection when turning screws. The angled tip helps to better align with the screw head, allowing for greater torque application and reducing the likelihood of slipping out of the screw head.

This design is particularly useful in applications where a strong, secure fastening is required, such as in aerospace assembly and maintenance, making it a common tool among aviation structural mechanics. The tapered shape also helps to self-center the screwdriver in the screw head, which aids in easier handling and reduces the risk of damaging the screw or surrounding materials.

While the other types of screwdrivers mentioned have their own specific designs and uses, they do not feature the blunt tip and angled profile that define the Phillips screwdriver. Flathead screwdrivers have a flat tip and are used with slotted screws; Torx screwdrivers feature a star-shaped tip for better grip and torque; and hex screwdrivers are used for hexagonal screws, which have entirely different applications and are not designed with the 30-degree angle characteristic of Phillips drivers.
