The KEY-REX NUT is not just tamperproof, vandal-proof, and tamper-resistant.
Key-Rex nuts are the world's most secure, tamper-proof nuts on the market. Every set of Key-Rex nuts are custom "keyed" for the client. Only the client has the sockets to fit their custom set which are designed to be nearly impossible to remove without the socket.
Key-Rex shapes are created using an encryption process that builds a shape out of millions of variables and defines a unique code for each part. Customers pay for a one-time key code tool and licensing agreement.
