GRK Fasteners is a brand we have been selling in the Weatherwise Cedar Products store for only a short while, but we are extremely fond of the quality and structural capabilities of their products. They are designed for doing a job efficiently with very few if any complications.
At the bottom of the screw is the Zip-Tip, which creates no need for pre-drilling, and allows for faster penetration. The W-Cut on the bottom part of the screw acts like a saw, creating a smoother drive with low torque. Close to the top of the screw you will find the Cee Thread. This part of the screw enlarges the hole which reduces the chance of splitting. The Recessed Star Drive on the screw head allows for zero chance of splitting to occur because of the six contact points. The Washer Head creates greater holding power. Reverse thread on some of the job-specific screws prevents mushrooming from occurring.
The many great aspects of these screws allow for twice as many GRK screws to be used per battery life of a screwdriver. All GRK screws have been evaluated for structural values with IBC/IRC specification. They are AC257 code approved for resistance to corrosion because of the Climatek coating used to further extend the quality of these screws. You can feel confident using these screws thanks to the limited Lifetime Warranty that comes with them. With a complete line of fasteners for many different applications and a very large size range, you can’t go wrong choosing one of GRK Fastener’s products.
