Ratings & Reviews for Grip-Rite PrimeGuard Plus #9 x 3-in Wood to wood Deck Screws 309 -Per Box

quality item

Screws are durable and the star head makes it much easier to drive. Price is pretty much the same no matter where you purchase. I am not sure why screws are so expensive but these type are. Thanks to Lowes for the military discount because it helps.

Consistent quality

Bought 2, 5 lb boxes to do my project. No bad or wrong sized screws in either box. Also none bent or broke. Did well with either treated or untreated material

Perfect for outdoor projects

I'm building a shed and used these instead of nails. They are the only way to go. They are fast and strong. The torx tip never strips even if your drill isn't straight. I would use gen on any outdoor project.

I went through 2-large box's of these screws. No problems noted. I used the last screw finishing my deck project today.

Strong

Used them on my fence, they are a quick starting screw that has great pull.

3" Star drive screws

I like this type of screw, they don't strip out like the phillip heads do. I wish Lowe's would carry a 4" Star drive. At present I have to purchase the screws from a competitor, which charges more.

Great product

The screw worked great for the fence I was building. heavy duty and easy to install with the star bit. Had less slippage than a Phillips bit.

These screws are for the pro, with a good bit, they speed up the time of putting together many projects,alot better then square or phillps screw's, very good product

Overpriced

I found the same product $10.00 cheaper in an independent lumber store.

Head sinks too far into green treated deck wood.

Treated lumber as bought from Lowe's is wet and soft. It is hard to stop this screw from sinking way too far into the green treated wood. If the treated wood was dry it might work fine but who had the time to dry the treated lumber. Next time I will try a drywall screw gun. This screws themselves seem fine.

Okay but not great

Several of the screws were not usable do to the heads..Out of the carton we used about2/3rd the rest were thrown away....

Star-drive deck screw

Used these screws on a deck project and worked very well. No problems with use of star bit and quality of entire box of screws was great.

The best!

These are the best really for any kind of construction as the star heads never strip out. Tough and rarely have a head snap off.

shoulder on screw is too short

The shoulder of these screws are too short and the threads come too far up on the screw. This creates a problem say when you are screwing 2 2x4s together, it pushes the first 2x4 away from the 2nd causing a gap between them. You can't always be in a position to apply enough pressure to hold the 1st one against the 2nd 2x4. The screws you use to sell were perfect, longer shoulders shorter threads. Who ever your purchasing agent is, well they need another job if they could not figure this one out,...
