One Way Round Head Sheet Metal Screws
Tamper Resistant 18-8 Stainless Steel Round Head One Way
One way round head sheet metal screws get their name because of their drive style. The head of the screw features a slotted drive that is designed to instantly cause cam out if the driver is turned in the wrong direction. This is achieved by manufacturing the drive in quadrants that are gradually raised to accept the driver bit when turning the screw right, and reject it when turning the screw left. The One Way drive makes installation of the screws easy, requiring only a standard slotted bit, but removal of the screw difficult (if not impossible) without the corresponding bit or a specifically designed removal tool.
One Way Screws are commonly seen in public areas such as bathroom fixtures and partitions, 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. One Way Screws are particularly difficult to remove, which means that they should be used for long lasting applications.
