Product Overview

GRK's R4 Self Countersinking screw has 6 self-contained cutting pockets which act like a router and transport the drill dust away from the edge of the screw hole. They also widen the countersink hole only around the head shape. The screw head top closes the hole exactly, leaving no damaged fibers around the wider area of the head. The R4 head design is so effective that it will not crack even the most brittle materials.
  • For use in wood, particle-board, cement fiberboard, plastic, sheet metal
  • Self-tapping
  • Self-countersinking head
  • No pre-drilling
  • No stripped heads
  • Common project applications: remodeling, fencing, storage, cabinets, framing

Thisbis the third time I have used the GRK brand screws as they are great fasteners. The first time I used GRK brand fasteners I was attaching thin hard wood boards from pallets to a building as siding. The fasteners used previously were the thinnest deck screws but each needed predrilled or the would split at the ends. When I switched to the GRK brand screws the trim heads worked fine and held the boards in place without splitting. The next use with the GRK brand screws were withe an earlier addition on the deck I used the R4 General Purpose screw which worked very well going through the 1 x 3 pine firring stripps used for a lightweight deck. And finnaly the current project an addition to the existing deck in which I'm using the GRK cabinet screws in which I bought purley out of curiosity on its holding power. In all events I was impressed with several things 1 comes with a functiong bit. 2 the heads were resistant to stripping out. 3 the ease of which each screw passes through the wood and grounds the meeting wood pieces to each other. Creating a firm fastening capable of being walked on without pulling out.

This line of screws is well made and very consistent, with the coating even, especially in the screw head, so I had no slippage even with 550 screws installed.
