12/14 x 5-5/8 GRK R4 Multi-Purpose Screws, Climatek Coated, Flat Head, Star Drive - 4AR83

12/14 x 5-5/8 GRK R4 Multi-Purpose Screws, Climatek Coated, Flat Head, Star Drive - 4AR83

GRK’s R4™ screws have some of the most advanced technology around for faster screw driving with a whole lot less effort and no pilot holes are required. Pilot holes are only needed if the building material manufacturer requires it. Always check with the manufacturer’s literature for installation recommendations. The patented nib design under the head acts like a saw blade with six self-contained cutting pockets. So you can countersink these screws into even the hardest of exotic woods. The threads are extremely aggressive, so they can even be used on fibrous material like OSB. The screws 2" and longer also have a “CEE” four threaded portion that enlarges the hole, reducing friction and increasing the “drawing strength” for the non-threaded portion making the longer screws much easier to drive. These screws can be used in all woods and plastic applications without shredding or cracking the surface. The 90º angle under the screw head fits perfectly into “pre-countersunk” holes for hardware brackets making these great for hinges and locks. They can also be used for decking, stairs and general residential construction. Equipped with Star Drive recess. Select pack size from drop down above. Imported.
