Patent attributes
According to example configurations, a modified screw head includes one or more slots or grooved channels. A screwdriver device includes a tip that can be inserted into a cavity in the head of the screw to torque the modified screw into an object. The screwdriver device includes a sleeve. The sleeve slides along a shaft of the screwdriver. The sleeve includes inward protruding posts (e.g., pins, fingers, etc.). Sliding of the sleeve over the screw's head requires that inward protruding posts in the sleeve be aligned with the grooves on the sidewall of the screw's head. Subsequent to aligning and sliding the sleeve into the grooved channels of the screw's head, the user twists the sleeve to secure the screw head to the screwdriver's tip. The sleeve can be spring-loaded to pull the head of the screw toward a handle end of the screwdriver after a user releases the sleeve.
