Security screws, also known as tamper-resistant screws, are specially designed screws that provide increased security by preventing unauthorized removal or tampering.

The distinguishing feature of security screws lies in their thread design. They typically have unique protrusions or slots that can only be rotated or removed using specific tools or lock mechanisms. This means that even if someone attempts to use regular wrenches, torque locks, or other tools, they would be unable to rotate or remove the screws.
