Tamper screw is a high security fastener that is designed to be removed only by the use of special tools. These are a good solution for protecting against minor vandalism or theft, and can cost less than a lock in some situations.
Some tamper proof screws are a notch above standard tamper resistant screws. They can be more difficult to remove without the proper tool and may need a unique, proprietary driver to be installed.

These screws are used in places such as hospitals and school campuses, to prevent theft and vandalism, as well as to discourage children from causing damage to the property and equipment they are using. They are also used in shops to help ensure that goods and services can be safely and securely sold.
There are several types of tamper proof screws available, including the varieties. These are a six-sided star configuration and have a central security pin in place that prevents the driver from working.
Many tamper proof fasteners are manufactured from heat-treated alloy steel with zinc plating, or 18.8 stainless steel. They are available in a variety of lengths and thread sizes to suit your application.
Some tamper proof fasteners require the use of a specially modified Allen wrench with a small hole drilled in its end to accept a protruding pin in the head of the screw. These tamper-resistant screws are often used in the automotive industry to help ensure that unauthorized access can't be achieved by untrained mechanics. They are also used in aircraft and military vehicles, to help protect the lives of those on board.
