Tamper-Resistant One-Way-Drive Steel Round Head Screws
 |
Install these tamper-resistant screws with a common slotted driver. Once installed, the drive's sloped walls cause drivers to slip, making these screws difficult to remove without one-way screw removers. They're often found on public facilities, such as restroom partitions and other long-term installations, where tamper resistance is important and removal for maintenance is unlikely.
Length is measured from under the head.
Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
One-Way Screw Removers—Extract one-way screws. With two pins on the driver's end, they grip one-way screws to loosen them when slotted drivers just slip.
