Stafast T-Nuts are an economical method of fastening a metal mechanism to a component that is made of wood, plastic, particleboard, or pressboard, or for anchoring wooden components to each other. T-Nuts consist of a flat flange with a cylindrical barrel which is threaded to allow a bolt to engage the T-Nut. Prongs often extend from the flange to grip the material into which the T-Nut is being inserted.
