  • Excellent structural screws
  • July 29, 2014
  • Recommended Product

Drills its own pilot, clearances the top board, doesn't cam-out or strip. Excellent for framing. Not just deck framing, but other tough joints where nails won't keep things together.

Pros Easy to Install, Nice Design

Really tough screw that I would feel comfortable building nearly any wood structure with. They bit into the wood easily and the large flat head kept it from pulling into the wood. I closed in one bay of my barn by anchoring 2x8's into the vertical support beams. These screws worked flawlessly. I wasn't too keen on the star pattern in the end of the head because it requires you to have a special bit. Even though one is supplied with the box of screws, if that one got worn or lost I would not have another to finish the project with. I will say the star driver worked well and didn't slip at all. Also these screws are rather expensive, but the only other option I found was lag screws. I would recommend these if you can stand the price.

Used these instead of lag screws when constructing outdoor propagation benches and an outdoor workbench. Quick and easy to run into pressure treated lumber. Designed to really snug up pieces. Store had these in 12-packs.

I needed to replace the fence around my farm and the wife wanted fence boards on 5" wood fence posts. I used a 3/16" pilot hole so I could align the ends of the 1" x 6" PT fence boards and keep the screw going straight. These are an engineering marvel, the shaft hole cutter keeps it from binding in the board, the washered head also has a cutter to recess it into the wood to avoid compressing, makes a nice clean looking attachment.

  • These GRK screws ROCK
  • September 27, 2016
  • Recommended Product

As the others have said, these things are great. Large threads, heavy duty, self drilling, easy to screw in. I too was leery of the star drive but it works flawlessly. After my deck project with these, as well as other deck board screws with the star drive, I will admit I am no longer a "square drive only" snob. The star drive is mighty fine. These screws are the bomb!

Pros Durable, Easy to Install, Good Size & Weight, Nice Design, Sturdy Cons pricey

Very easy to drive with the bit provided. I did drill a small pilot hole but it appears that would not have been necessary as screw does a good job on its own. I used this product for some repairs and it did the job and then some. Very sturdy and I don't think I will need to repair again as opposed to the traditional screw used originally.

I used these screws to secure a 2 X 12 to existing house structure. Using my air ratchet the screws easily drove into the 2 x 6 wall structure, there were no broken or twisted screws of the 32 that I used.

Garbage. I decided to save some money per fastener on my huge deck project. The fastener heads are too soft and the bits fit too loosely and end up stripping out the torx style socket. Then you can't remove the fastener or run it in. I was using these to secure 2x8 treated to 4x4 treated posts. you better get it right on the first pass or your in trouble. I had to grind down a torx bit to get to a wider section so the bit would grab the remaining socket teeth on the fastener. These are going back today! This fastener uses the same size torx as the coated deck screws I'm using and they don't strip out! Hex heads are the way to go, FASTEN MASTER LEDGER LOK"s . no problems whatsoever.

I have never had good outcomes with these. About 1 in 3 strips out. I have been trying to use them on a few arbor projects-basically mounting a 2x8 onto a notched 6x6 post (board and posts are pressure treated). I have tried using the included driver bit and bought bits from other manufacturers. The star shape on the bolt strips smooth on just about every third screw (so I cant even remove the half-driven screw). I have had this issue with my Dewalt impact driver as well as with my Dewalt drill set to Hammer setting on speed 1,2 and 3. I'm convinced it is the quality of the metal. I have wound up predrilling every board and STILL the heads strip out.So I then have to hammer them in the rest of the way.
