What is a stripped screw hole and how does it occur?
A stripped screw hole is a condition where the screw hole in a material, such as wood or metal, becomes damaged and can no longer hold a screw in place. This occurs when the screw is over-tightened or when the screw is removed and reinserted multiple times, causing the threads in the hole to become worn out or stripped. As a result, the screw will no longer fit snugly in the hole, and the surrounding material may be weakened.
To avoid stripping a screw hole, it is essential to use the correct screw size and type for the material being worked with. Using a screw that is too large or too small for the hole can cause the threads to become damaged. Additionally, applying excessive force or using a power tool with too much torque can also lead to a stripped screw hole. To prevent this, it is crucial to use caution and care when working with screws, and to follow proper techniques for screw insertion and removal.
How do I identify a stripped screw hole?
