STANDARD-SECURITY LEVEL
Penta head bolts made of 18-8 stainless steel.
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 High-Security Key-Rex® or Penta-Plus® bolts.
The savings in loss prevention can be significant. Cities and municipalities who have specified and used our High-Security drives experienced a significant reduction in copper wire theft — some have even achieved zero theft altogether.
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.

Patented design provides tight tolerance between bit and screw for a “stick-fit”. Screws don’t fall off the bit, even when bearing weight – perfect for assembly applications.
Fast indexing, ease of use and improved installation times are the result. Looking to make gains in productivity and efficiency with a security screw? This is it.
