Penta-Plus™

Bryce Fastener - Penta Plus Tamper-Proof Screws & Bolts (Second Only to the Key-Rex™)
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 laptop computers in open kiosks, universities and city 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 and gripping power of this screw over any other on the market except for the Key-Rex.

Penta-Plus™ machine screws come in stainless steel and are used in tamperproof applications requiring threads. The handle more torque than other vandal-proof screws and can be tightened more securely. They can be power driven. The penta-plus socket is extremely secure. The combination of these features make them one of the most economical tamperproof fasteners for high production security applications.
