PATENTED HIGH-SECURITY LEVEL
Penta-Nut™ security nuts have the largest diameter compared to other available anti-theft nuts and security nuts, and with the added Raptor™ Security Head, no washer is needed. These high-security, 316 stainless steel, tamper-proof nuts, turn any bolt into a lock.
When manufactured with the optional Raptor™ Head, the Penta-Nut™ Security Nuts can handle 20% more torque. Also, by adding the Raptor™ Head, these tamper proof security nuts provide more grip than any other tamper proof nuts and security nuts on the market.
Key-Rex can be made for virtually any fastener type, any size, any metal, any coating, and more. From galvanized metric bolts for harsh coastal outdoor environments to heat-treated, micro screws for data center security.
