(35900)9 x 1-5/8" Cement Board 1200pcs

I remodel bathroom and kitchens and this screw is far better than anything else on the market. The heads don't torque out like many of the competitor items and there is a brown version of this screw that's horrible. This "lime green" version is the best! Better than the square head backerboard screws as well. I was very disappointed that the product wasn't available for an extended period of time. Thankfully they're back and hopefully for good. A box of 1200 lasts me about 4-5 bathroom depending upon size of shower. We only use Hardi backer board and never skimp on materials.

I gave these screws four stars because of their design. They have a very flat head with raised grips on the shank just under the head to help it hold in the cement board. I knocked off one star because not all screws embedded fully in the Hardiebacker cement board that I was using in a ceiling application and some screws stripped. Now that being said, I am just a do-it-yourselfer that may not have been using the proper techniques so it could have been user error. Overall these screws seemed to have excellent build quality and design and I would highly recommend them to anyone.

These well engineered screws are the best I have found and I have been using them in my tiled shower building projects for a few years now. The screw head is large and countersinks easily into the cement board, making for a secure application. The coating is a very effective waterproofing and the bright color makes it easy to spot any missed fastening spots. What's more the plastic container is well made and useful for storing other things after all the screws are used up. All in all another great product from Phillips Fasteners.

These are the best screws in the universe for CBU's. Great for all rock board. I don't use HardieBoard, so I don't have an opinion on it. Lowe's quit carrying them; (thank goodness, they were overpriced and only in a box of 100.), so I turned to faithful Amazon. In a box of 1200 and half the price! What more could you ask? Phillips has a great product in these. Thanks.

Great product and customer service from Phillips. I needed more for my project(s). Of course I purchased these at Lowes only to find that they no longer have them in stock. So it was Amazon to the rescue again. FYI: since these are made to hold down cement board and resist moisture, I have used them on all my outdoor projects with no rusting or staining.

Great value

I'm a contractor who uses these screws religiously with cement board. The head is much larger than other cement board screws which improves their grip. Better grip means no coming back for cracked grout later on, and happier customers as well. I order these from the website when needed, but have 20 boxes in storage just in case something comes up.

Fantastic screws! These sink in nice without striping. Comes with two bits under the label. I think these will be discontinued, replaced by Phillips PLUS with the blue bits. So if you are a fan of these which are tried and true, its time to stock up now.
