Tamper-Resistant One-Way Binding Barrels and Screws
Stainless Steel
Black-Oxide Stainless Steel
Install these binding barrels and screws with a standard slotted screwdriver, but they require a special tool to remove. One-way removal tools are sold separately. Made from 18-8 stainless steel, these binding barrels and screws are chemical resistant and may be mildly magnetic. Barrel length and screw length are measured from under the head.
Black oxide binding barrels and screws have a matte-black finish that matches dark surfaces and reduces glare.
