Features of insert nut: These threaded inserts are inserted into a pre-drilled hole by screwing in, in that case the external protrusions bite into the wood, preventing the nut from either turning or pulling out.
PS:1. The hole depth is 1-2mm longer than furniture screw; 2. If that hardness of the wood material is high, enlarged a little bit the screw hole to fit the screw.
