Lags that can take immense torque
Lag Thread Security Bolts
Raptor Security Head Included
Standard-Security and High-Security Options
If you need a powerful driving security screw with extra strong hold, our High-Security Key-Rex® or STYKFIT®7 Lag threaded security screws will exceed your expectations. Lag screws are rarely made into security screws because most security drives are not powerful enough to torque the screw without failing. Bryce Fastener’s Key-Rex® and STYKFIT®7 security drives far exceed the required torque. This is important because security Lag screws are used in high torque applications such as pressure treated wood, concrete lag inserts, and pre-drilled plastic. Bryce Fastener’s security Lag bolts have been specified for wood signs in many National Parks. Our Lags are manufactured with an oversized Raptor™ Button Head. This helps them hold better in wood than standard Hex or Penta Head security lag screws.
Standard-Security level Penta Head lag bolts are available by special order.
