Description
xGRK's R4â„¢ self-countersinking screw has a patented under head 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 an ideally clean hole into even the most brittle materials without cracking any surface treatment. This design enhances the R4â„¢'s versatility by allowing the fastener to countersink into even the hardest woods. The head of the screw closes the hole off with precision, leaving no damaged fibers around the head. R4â„¢ screws 3-1/8 in and longer have a four-threaded CEE thread. This enlarges the screw hole for the non-threaded portion of the fastener, allowing the wood to settle easily. It increases the screw's drawing strength and reduces the friction on the screw shank that lowers the driving torque.

If your product is shipping Freight, it will be indicated during check-out as "Freight Shipping." If your product is shipping Freight and Free Shipping is not offered for that specific product, you will receive a separate shipping invoice for you to accept or decline.
