Caliburn™ Concrete Screw



For Concrete & Masonry Applications

  • Available in Bugle, Pan & Washer Head
  • An Anchoring System In Itself
  • Professionally Engineered


Caliburn™ screws are professionally engineered fasteners for concrete and similar applications to resist static, wind and seismic tension and shear loads in cracked and uncracked normal-weight concrete and sand- lightweight concrete. Anchors may only be used for redundant applications, where multiple anchors support linear elements (e.g. ductwork) when designed. The aggressive thread pattern creates a track that burrows into concrete and is designed for trapping excessive concrete dust thus keeping the threads sharp.  They feature a patented thread design for ease of driving the screw.  The Caliburn™ is Climatek™ coated for high corrosion resistance.


Case Hardened Steel

Star Drive Recess that eliminates stripping

Aggressive thread pattern traps dust and carves into the pre-drilled hole making both the hole and the screw reusable for future adjustments!

To Use:

Pre-drill pilot hole with 3/16" Concrete Drill Bit for Caliburn™.

Clear concrete dust from hole.

Drive the screw with GRK #30 or #40 bit (as required by style of Caliburn™)
