## Overview

The GRK772691001412 is a 4-inch self-tapping screw featuring a Climatek coating for enhanced weather resistance. Designed for easy installation without pre-drilling, it works flawlessly with various materials, ensuring a reliable and efficient fastening solution.

## Description

GRK's R4 self countersinking screw has a new underhead with saw-blade like cutting teeth and six self-contained cutting pockets. Together they act similar to a circular saw-blade, transporting the drill dust away from the edge of the screw hole while cutting a perfectly clean hole into even the most brittle materials without cracking any surface treatment. This design also further enhances the R4's versatility by allowing the fastener to be installed without countersinking into even the hardest woods. The screw head closes the hole off with precision, leaving no damaged fibers around the head.
