What is a tamper-resistant security fastener?
A tamper-resistant security fastener is designed to have a feature that protects it from being removed without a specialized tool. Used in applications where theft or vandalism is possible, these features protect what is being fastened from removal. Common security drives are Hex or 6-lobe (Torx) recess with a pin, a spanner drive and a one-way slotted drive. Most common are security screws and security nuts.
