The theory behind tamper-resistant fasteners is to make a fastener whose loosening requires a tool that a tamperer is unlikely to have on hand at the time of opportunity for tampering. There is no expectation that it will be impossible for a tamperer to obtain the driver. Rather, the main idea is simply that most tamperers will not bother to seek out and obtain a driver. In the cases of vandalism prevention and theft prevention, since most vandalism and theft incidents are simply crimes of easy opportunity, the idea is to “raise the bar” and make the opportunity less convenient.
A tamper proof fastener takes the theory one notch further. Some tamper proof screws require a tool that is proprietary and can only be obtained with the purchaser submitting documentation as to its intended use. Others can be installed with standard wrenches, but when tightened to a specific torque head shears off, leaving a conical, round, or flat head design that completely protects your property.
