Ratings & Reviews for GRK R4 #9 x 2-in Polymer Exterior Multi-material screws 330 -Per Box

Screws were poorly manufactured. Drill tips were improperly placed too far up the shank of the screws. To drive them in without a pilot hole took forever. The only way to use them was to start with a hammer. Poor quality.

Go to Screws!

By far, these are the best quality on the market. The bit holds tight and will not strip. The screws are sharp and will drive the screw completely through the board (not that you want to do that). I buy the big box. Lowe’s has a discount if you buy two boxes.

Great!

Love these screws. Have used three big boxes on the construction of my home. Not one has sheared. Drives in straight. They are strong and easy to work with.

simply the best!

Grk are bar none the best screws on the planet, the included bits are strong and dont fail, better than any purchased, love the bright color, easy to find, they go in, come back out and never strip or fail, i will never buy another brand as long as grk are available, they are simply the best!

Say goodbye to stripped out screws!

You will eliminate all of the stripped out screw heads in your future projects thanks to the star shaped screw head design (bit included). These drive smoothly with little effort and are offered in a variety of sizes. I highly recommend the GRK brand of screws.

skepticle at first

Without a doubt the best screws Ive ever used. Seems weird to brag on a screw but these are worth the money.

Half are dull

I’ve been a fan of GRK screws since I first tried them. This box was the first that has really disappointed me. Before this one they were honestly the best screws you could ask for. Started easy, the heads were all well formed and didn’t strip out or spin out. This batch still has the quality of the heads but the points are dull to the point that it’s a chore just to get them to start in the wood. Never had this experience before with GRK and I hope it’s just a fluke batch and not a sign of drop...

Great screws ariubd my house

I use these everywhere. The join two 2x4’s solidly. This type of driver does not strip like a phillip head.

great construction scres

Excellent performance- self drilling, self countersinking with sharply defined and non-dimpled hole for the screw head; driver bit included but couldn't find this described on the case so I needlessly purchased a screw bit.

Approved for termite resistant wood

This brand promotes that it is approved for termite resistant wood and I live in Los Angeles where termites Thrive because we don't have winter. Included is the Star drill bit

great product, super strong and self drilling.
