Final answer:
Torn (Torx) and Robertson screws were developed to enhance the functionality of screws by increasing the holding power, preventing the screw head from stripping, and ensuring a more secure connection.
Step-by-step explanation:
Torn and Robertson screws were developed to increase the holding power of screws, reduce the risk of stripping the screw head, and provide a more secure connection.
The design improvements allow for a tighter fit between the screwdriver and the screw, which leads to better torque transfer and decreased chances of cam out (when the screwdriver slips out of the screw's head). The Robertson screw, for instance, has a square-shaped recess that reduces slippage and stripping, while Torx screws have a star-shaped pattern that provides a more stable grip. Both designs contribute to a more efficient assembly process and are widely used in various industries, including construction and electronics.
