Proprietary Technology

Six innovations that make GRK the professional's choice for construction fasteners — engineered for faster installation and unmatched holding power.

W-CUT Thread Technology
W-CUT Thread Technology
Less splitting

GRK's proprietary W-CUT thread design features alternating high and low threads that cut through wood fibers cleanly, reducing splitting and requiring significantly less driving torque than conventional screws.

Climatek Coating
Climatek Coating
Lifetime guarantee

Industry-first Climatek coating provides a lifetime guarantee against corrosion. Approved for use in ACQ, CA-B, and other pressure-treated lumber, making GRK screws ideal for SW Florida's humid, salt-air environment.

RSS Rugged Structural Screw
RSS Rugged Structural Screw
10x faster install

The RSS replaces lag screws and through-bolts with no pre-drilling required. Code-approved structural fastener that installs up to 10x faster than conventional lag bolts while delivering equal or greater load capacity.

Self-Countersinking Head
Zero cracking

Under-head cutting teeth act like a circular saw blade, countersinking into even the hardest woods with zero surface cracking. The screw head closes the hole with precision, leaving no damaged fibers.

Zip-Tip Self-Tapping Point
No pre-drill

The Zip-Tip eliminates the need for pre-drilling in most applications. This precision-engineered point bites into wood immediately, reducing wobble and providing a fast, one-step installation.

Star Drive Recess
Zero cam-out

Six-lobe Star Drive recess provides superior bit-to-screw engagement, virtually eliminating cam-out. Every GRK screw 2" and longer includes a free Star Drive bit right in the box.
