Product Overview

The R4™ self-countersinking screw from GRK Fasteners has a patented underhead with saw-blade-like cutting teeth, as well as six self-contained cutting pockets. These features work together as a circular saw blade, moving drill dust away from the screw hole's edge while simultaneously cutting a perfectly clean hole, even into the most brittle materials, with no surface cracking.

Key Features

  • Fast bite tip eliminates pre-drilling and provides a fast start for one step installation.
  • W-Cut™ low installation torque allows for fast driving and ease of install.
  • Precision fit between R4 Multi-Purpose screws and GRK bits reduces wobble and improves productivity.
  • For use in wood, particle-board, plastic, sheet metal, cement fiber board, wood decking, composite decking, and melamine.
