Why use GRK Screws?

GRK Screws are packed with unique features, saving you time and money:

  • CEE Thread enlarges the screw hole, increases the drawing strength, reduces friction, lowers the driving torque and reduces splitting
  • Drive into hardwoods and softwoods easily without pre-drililng
  • W-Cut™ Thread Design - patented design acts like a saw blade, cutting through fibrous materials and reducing the amount of torque required to install the screw
  • Zip-Tip™ - designed for fast starts in any fibrous materials

GRK Screws won't fail where others do, driving in effortlessly and significantly reducing the installation time

Climatek™ is exclusive to GRK products. Originally designed for the Navy, GRK has adapted this coating for fasteners and rigourously tests it to meet and exceed all standards. GRK's Climatek™ coating is virtually indistinguishable from brass and its colour matches almost all wood finishes.

GRK Fasteners revolutionary Climatek™ coating is available only on GRK products.

GRK's Climatek™ coating consists of a total of six layers of various materials, including three layers of zinc-polymer.

Climatek™ has been tested for salt spray resistance, and more importantly, for Kesternich durability. Kesternich cycles are a more advanced way of testing a coated material. Each Kesternich cycle simulates heat, cold, wind, water, salt as well as a variety of other elements, whereas salt spray merely uses salt water for its tests.

Climatek™ passed 29 Kesternich cycles, making it the most advanced coating of its kind.

PHEINOX™ stainless steel products are hardened and come with a limited lifetime guarantee against staining and rusting.
