  • Screw-in type: Screw-in insert nuts have an external thread and hex head and are screwed in with a Flat Blade Screwdriver or an Allen wrench. The screw-in insert nuts come in various sizes and take different screw sizes. For example, an M6 insert nut will take an M6 bolt, a "1/4-20" insert nut will take a 1/4-20 inch bolt., etc The pre-drilled hole must be as deep as the length of the insert nut plus any portion of the bolt that may be screwed past the end of the nut in the work piece.
  • Hammer-in type: Hammer-in insert nuts, also known as knock-in nuts, are lined with barbs and are hammered in. They are often made of steel, brass or nylon. They are designed to work in wood and particle board.
