M6 threaded inserts for wood, MDF and other man-made boards. The body of the insert is 12mm long with a 10mm overall diameter. One end of the insert has a slot to accommodate a wide-bladed screwdriver for insertion. The M6 insert requires an 8.5mm or 9mm pilot hole; the optimum diameter is dependent on the hardness of the material you are using. We found 9mm worked best in MDF. We offer these mainly for making custom jigs. We have also found them to be a useful and very effective solution for repairing flat-pack furniture.
