Can a screw be Rethreaded?
To restore bolt threads, start by finding the thread count (SAE) or pitch (metric). Don’t try to rethread the entire bolt, hole or nut in one operation. Insert the rethreading tap or die and rotate a few turns, then back it off a full turn. That will dislodge the debris from the teeth.

When do you use threads instead of screws?
Screws are typically used for securing mating parts. When two pieces are joined together using screws, one piece is made with threads, and another piece is made with clearance holes, which have bigger diameters than that of the screws.
Is there a way to repair damaged threads?
All you need to repair damaged threads is some patience and a tap and die set. Threaded holes can be found in all areas of your vehicle, from the engine to the chassis. These holes are tapped with the correct size of threads for the job at hand.
