A screw won't work if it doesn't have anything to grip onto. Using screws on sheet metal or on other thin or soft surfaces can cause the screw to back out or lose its grip. A screw thread insert solves that problem by offering a receptacle for the screw to go into. An insert with a threaded interior will hold onto the screw, keeping it in place. Screw thread inserts work in a similar way that nuts work with bolts. The inserts are small and inexpensive, but can make a big difference in your next installation.
