Features and Benefits

Features and Benefits

 N/A In metal applications, T-Nut Fasteners are typically spot-welded or projection-welded, with the flange attached to a base plate. They may also be snapped into holes. Either way, they obviate costly tapping and simplify design. In non-metallic applications, T-Nut Fasteners are usually driven into holes. They may provide threads and add strength to relatively weak materials. Some T-Nut Fasteners for non-metallic applications may be fed and applied automatically.
