Screws Easily Driven With A Slotted Screwdriver - Very Difficult To Remove

One way security screws are distinguished by having an unconventional drive, making tampering with the screw more difficult, if not impossible without the matching driver. One way screws are used for securing materials from being tampered with or stolen. You will often see security screws used in bathroom stalls, particularly toilet partitions and other public locations. Security screws in this selection are grade 18-8 or higher stainless steel, which prevents rusting and is corrosion resistant.

One Way Security Screws

One Way Screws get their name because of their drive style. The head of the fastener features a slotted drive that is designed to instantly cause cam out if the driver is turned in the wrong direction. This 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.
