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.
SECURITY LEVEL:
Penta-Plus™ has proven very
successful for universities, electronics
retail, and city government facilities.
