Penta-Plus

PATENTED HIGH-SECURITY LEVEL($100 Min. Order)

Penta-Plus™ has been on the market for 20 years and is our top selling product. Most sizes are stocked.

We manufacture our Penta-Plus™ drive in screws, bolts, and nuts. Penta-Plus™ has U.S. and worldwide patents. It's pentagon design is configured to keep Torx-Pin, Hex-Pin and all other tamper-resistant bits out. Standard tamper-resistant screws have bits sold on the open market where they're available to anyone. Only the matching Penta-Plus™ bit tip can fasten and unfasten a Penta-Plus™ screw. Penta-Plus™ is only available to Bryce Fastener customers and bits are controlled through our customer database. 

Without failure, our High-Security Penta-Plus™ has proven itself tamper-proof and vandal-proof in the most extreme situations; securing tablets and computers in open kiosks, protecting valuable property at universities, and in critical city and government infrastructure applications. Next to our most secure custom fastener, Key-Rex®, Penta-Plus™ is your best tamper-proof option on the market. We give you the option to add our Raptor™ Security Head to your order. The Raptor™ Head eliminates the need for washers and significantly increases the torque ability and gripping power of Penta-Plus™.
