The One Way screw drive style is also referred to as One Direction, Irreversible, or One-Way Slotted.

One Way Screws are commonly seen in public areas such as bathroom fixtures and partitions, license plate frames on cars, wall or floor mounted safes, and wherever tampering after installation becomes a security issue. Generally speaking, all Tamper Proof Screws are used to deter vandalism or theft because the removal of the screw is difficult, if not impossible, without the corresponding unconventional bit. One Way Screws are particularly difficult to remove, which means that they should be used for long lasting applications.

One Way Machine Screws feature a chamferred tip, and are commonly used with flat washers and nuts, as well as driven into tapped holes. They are made of industry standard grade 18-8 Stainless Steel which is corrosion and rust resistant.
