Description

GRKs R4 self-countersinking screw has a new under head with saw-blade like cutting teeth and six self-contained cutting pockets. Together these features act like 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 further enhances the R4s 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.

R4 screws which are 2″ and longer have a four threaded CEE thread that enlarges the screw hole for the non-threaded portion of the fastener. This technological advancement allows the wood to settle easily and increases the screws drawing strength, reducing the friction on the screw shank and lowering the driving torque.

The R4 is a multi-purpose screw that can be used in all woodworking and plastic applications. Because the head has a 90 degree angle at the underside, the screw fits perfectly into the pre-countersunk holes of hardware fittings such as hinges or locks. Stocking of different screws is no longer necessary because the R4 is a very versatile screw.
#6 and #8 screws use T-15 bit; #9, #10, and #12 use bit T-25
Self-tapping, countersinking head; W-Cut thread design
One pail contains 820 screws
