Anti-theft bolts are bolts that are proven to be tamper resistant, making them optimal for high-security applications. Since they have drive heads that are more unique in nature to prevent any form of tampering, the tools needed for their installation and removal are also specialized in nature. As a result, they are often found in automotive parts, public fixtures and electronic enclosures, offering great protection against theft, while also maintaining structural integrity.
