What is the shear strength of these screws?

Asked by: Calybuilder
I built a 4ft tall by 10 ft long water tank using 16" oc studs with 2 3" #9 Deckmate screws. The force of the water sheered the screws. I rebuilt the tank using 3/8" lag bolts.

#9 x 3 in. Star Flat-Head Wood Deck Screws (5 lb.-Pack) is rated 3.6 out of 5 by 54.
Rated 2 out of 5 by from Screws to brittle Screws to brittle, The screws are made with a metal that is so brittle the head either snaps off or the threads actually shear off once fully inserted you can't get them back out . Of course if they head snaps off it's not holding anything and if the threads snap off it will be a nail.

Rated 1 out of 5 by from Screws rot out right under the head. Spent over $120 for all the deck mate screws I used on my deck project and after only 5 years they started to rot right under the head where there are no threads. They thin out in this area from rust and eventually the head pops out. Stay away from these screws and use stainless steel.

Rated 2 out of 5 by from Screw Removal after 16 years is an issue I am re-decking and removal of the old cedar deck is always fun, I have several versions of deck screws. The old DeckMate ASR - 3" #9 screws are a pain to remove. About 10% are snapping and they are all very corroded. At the same time I am removing some Grip Rite Deck screws also 3" #9 and they are still intact. So they are preferred over the DeckMate. Prior to the removal I bought 15.lbs of DeckMate deck screws. I will be returning them. I concur with the corrosion comments posted on here regarding DeckMate and corrosion, I am deciding between the FastenMaster and the GripRite products. Any collaborative commentary appreciated. I mean 16 years isn't horrible but they are not a LifeTime product.

Rated 5 out of 5 by from Tough heads & great threads! Perfect deck screw. Whether building a deck, or making repairs, this is the product to use. They hold where a nail can't grip, or where nails have come loose. Nothing more frustrating than repairing or refinishing a deck & having to hammer down hundreds of nail heads. That never happens with these screws. They drive in securely, due to the star drive's excellent grip & they stay in place. And, using these quality star screws, can make future repairs easier. Trying to pry out a deck nail can often ruin other boards, where these screws will back out years after installation. Just a plain ole great product. And, yes, they are expensive and, yes, 2 or 3 in the box may have so much coating on them that they are unusable. Still better than nails and they go in where phillips & flat head screws won't!

Rated 1 out of 5 by from These Corrode I used these screws and they corroded within six years and came out of my treated lumber deck boards. When I pulled them out they were rusted and the threads were gone.

Recently I had to remove the screws on a piece and they came out like cake with my impact driver. The star bit included is of good quality too, just don't lose it!

Rated 5 out of 5 by from Great for wood decks but be careful not to push... Great for wood decks but be careful not to push them to far into the wood if you use a impact drill. Use something else if you want it to be flush against a metal brace.
