Manufacturer of the world's most secure fasteners

penta-bolt tamper-resistant screws

STANDARD-SECURITY LEVEL

Penta-Bolt

Recommended for low value security applications

18-8 Stainless

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.
