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™ can handle 20% more torque, allowing for a wider range of applications. Also, by adding the Raptor™ Head, these tamper proof security nuts provide more grip than any other tamper proof nuts on the market.
Bryce Security Fasteners can be made in 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.
