The pull-out holding force is 1.7 times that of the drill screw, and the shear strength is 3.8 times that of the aluminum rivet!
The "Tornado Point" features a sharp, precisely formed screw thread that works like a drill during installation. It allows for one-touch fastening of thin steel plates ranging from 0.4mm to 1.00mm without the need for a pilot hole, suitable for a total thickness of up to 1.4mm for two sheets of thin steel, and up to 0.8mm for two sheets of stainless steel. Since it screws in without cutting, there are no chips produced, and the burr effect ensures a strong bond between the two steel plates. 【Features】 - One-touch fastening of thin steel plates from 0.4mm to 1.00mm without a pilot hole - Applicable thickness up to a total of 1.4mm for two sheets of thin steel, and up to 0.8mm for two sheets of stainless steel - No chips produced as it screws in without cutting - Burr effect ensures a strong bond between two steel plates - Pull-out holding power is 1.7 times that of drill screws, and shear strength is 3.8 times that of aluminum rivets *For more details, please refer to the PDF document or feel free to contact us.
