Can you put a nut on a screw?
Wood screws will not accept a nut as their thread type does not allow it. Nuts commonly used on bolts will not work on wood screws as wood screws are designed to thread into the wood. A T-nut or threaded insert is required where a threaded bolt needs to be inserted into the wood.
Are insert nuts strong?
They offer a stronger alternative to weld nuts and tapped holes, and they provide a stronger bond than self-tapping screws. In fact, threaded inserts are usually the strongest and least time-consuming fasteners used in any manufacturing setting, especially because they were designed for automation.

Simply drill a pilot hole, thread in the insert with a screwdriver or T-wrench, and use a machine screw or bolt to attach the other part.
Are threaded inserts stronger than screws?

Should I use threaded inserts?
