One Way Screws These Round Head Machine One Way Screws are made of 18-8 Stainless Steel. They can be installed with a standard, flat blade screw driver but can only be removed with a special removal tool. Many national retail stores continue to specify "One Way's" because they are still the most "Tamper-Proof" security screws available. Even with removal tool, this screw cannot be removed easily.
