Insert nuts provide strong machine screw threading in soft woods or substrates. External protrusions bite into the wood, preventing the nut from either turning or pulling out. 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. Join wood, chipboard and plywood with these brass fasteners which are especially useful in knockdown furniture.
