Ratings & Reviews for GRK R4 #9 x 3-1/8-in Polymer Exterior Multi-material screws 720 -Per Box

Container of screws

Contains exactly what it says and is easy to move around the job site. Saved money by buying in bulk.

Great bite, pull and dig

These drive in so nicely. They really bite quickly compared to other screws I've used. The heads have flanges that help to dig them in as well. If you're overeager, you can easily have the head over-drive into the material.

Very pleased

No stripping, no breaking and they hold tight. A little tip if to visit the clearance aisle and see if they are on sale. I bought two full containers after they had been marked way DOWN!

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.

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...

Best driving screws

These screws drive really well and seem to have plenty of pulling and holding power. They are a little pricey but worth it. The #9 screws seem to hold very well and not split wood. I'm not sure when the #10 version of this screw would be necessary unless required by code.

Excellent

Bought these for a major fencing project. They worked very well. All the tips were very sharp and the star heads were all perfect. Went in easily and did not split and boards even close to the edges. Would buy again

We use these everyday. Easy to use. AAA+++.

Our business is structural repair. We use these for literally every job we have done since we started. They are strong, reliable, and easy to get things done right the first time with. Also affordable. We have confidence in the strength it gives our work, providing our customers with peace of mind. Our number one choice by far. Stock up, you won't regret it.
