Anti-Theft Nuts (Security Nuts / Tamper-Resistant Nuts) are specialized fasteners designed to prevent unauthorized removal of bolts or equipment. Installation involves threading the nut onto a corresponding bolt or stud using the appropriate security tool or key, creating a secure connection that cannot be easily loosened with standard wrenches.

These nuts are commonly used in public installations, automotive parts, machinery, signage, and safety-critical applications where protection against tampering or theft is required. Available in materials such as stainless steel and mild steel, Anti-Theft Nuts provide high mechanical strength, corrosion resistance, and reliable long-term security in both indoor and outdoor environments.
