Description M3 8mm, thread forming screws and grease gun for OpenBeam (100 pieces)

This is a bag of 100 M3x8mm thread forming screws, 2ml SKF LGMT 2 all-purpose grease in syringe and screw manual . This set together with a hexagon socket wrench makes a nice thread forming tool. The screw with 5.5mm flange head in this set is designed to easily screw from the inside an aluminum beam with a 2.5mm hole . The trilobular head will form threads by deforming the aluminum. Threads are not formed by cutting. For a smooth thread forming process, a little grease is crucial. That's why we decided to sell these screws together with a syringe with 2ml grease (SKF LGMT 2).
