If the old thread-cutting screws have already created the necessary threads in the metal kitchen cabinets, you can replace them with regular screws that match the size and length of the existing threads. However, there are a few factors to consider before making this change.
Thread compatibility: Ensure that the thread pitch and diameter of the new regular screws match the existing threads in your metal kitchen cabinets. It's crucial to have a proper fit to maintain the structural integrity of the cabinets.
Material compatibility: Consider the material of the new regular screws. Make sure it is suitable for use with your metal kitchen cabinets. Stainless steel or brass screws are often recommended for kitchen applications due to their corrosion resistance.
Strength and durability: Thread-cutting screws are designed specifically for creating their threads as they are driven into the metal, resulting in a secure connection. Regular screws may not provide the same level of strength and durability, as they rely on pre-existing threads. This may affect the long-term stability of the cabinets, especially if the new screws don't fit tightly in the existing threads.
Before replacing the old thread-cutting screws, assess the condition of the existing threads. If they are in good shape and you can find suitable regular screws that match the specifications, it should be possible to use them. However, if there are any concerns about the fit, strength, or overall stability of the cabinets, it may be safer to stick with thread-cutting screws or consult a professional for advice on the best course of action.
