This screw is useful at deterring opportunistic vandalism such as within bathroom stalls. Because bits are readily available at most hardware stores the Hex-Pin™ is not recommended for securing items of value. Stories abound of Hex-Pin™ bits sold in retail stores being used to compromise something of value in the same store.

The Penta-Bolt™ is the staple of ground lid and manhole cover security, and is typically specified for these applications. It requires a special pentagon socket which is not found in retail stores. Unfortunately toolboxes are equipped to remove Penta-Bolt™ fasteners with common items such as locking pliers. Most notably, copper thieves are easily removing these fasteners. Penta-Bolt™ fasteners protecting copper should be replaced with something more secure. The savings in loss prevention can be significant.

Penta-Plus is proprietary to Bryce Fastener and configured to keep Torx-Pin, Hex-Pin and other tamper-resistant bits out. Tamper-RESISTANT screws have bits sold on the open market. The higher security Penta-Plus is considered tamper-PROOF because all bits are controlled by Bryce, maintaining its integrity as a high-security fastener. Without failure, the Penta-Plus has been proven tamper-proof and vandal-proof in the most extreme situations, including securing tablets and computers in open kiosks, protecting valuable property at universities and critical infrastructure city and government applications. Next to the Key-Rex, these are the most tamper-proof screws and bolts on the market. Adding the Raptor Claw option to the bottom of the Penta-Plus significantly increases the torque ability and gripping power of this screw over any other on the market with one exception — the Key-Rex.

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.
