1 bag with 100 pieces M3x8mm thread forming screws, 2ml of SKF LGMT 2 general purpose grease in syringe and screw set manual. This set together with a hex nut driver makes a nice threadforming tool. The screw with flanged 5,5mm head in this kit is designed for easy thread froming inside an aluminum beam with a 2,5mm hole. The trilobular head will form thread by deforming the aluminum. Thread is not formed by cutting. For a smooth thread forming process a little grease is crucial. That is why we decided to sell these screws along with a syringe with 2ml grease (SKF LGMT 2).
