GRK screws can actually save you money by reducing installation time and eliminating waste...
GRK Screws are considered to be the finest in the world, both in quality of materials and conceptual engineering. GRK screws are designed for use in decks and other industries using hard or soft woods. Their uses are almost unlimited due to their superior qualities. A special hardness is achieved through a fine tuned heat treatment process that makes GRK screws virtually unbreakable.
GRK screws can considerably reduce total installation or assembly time. They are easy to install, as no pushing is required to keep the bit in the head of the screw; which also means that there are no cam out problems and there is less friction due to their lubrication. GRK screws back out as easy as they go in and do not suffer from head twist off, strip out or screw breakage; problems that most contractors encounter every day.
