1-1/2 in. Lattice Sierra Cedar SS Screws (12-Piece/Bag)

A:  Hello, please reference our Installation Guide under Info & Guides. Thanks!

A:  No, unless you first bore an oversized hole in the concrete and set a lead or plastic anchor in the hole that is sized for these screws. These screws are not designed or intended to penetrate concrete.

A:  I don't believe they would work in concrete.

A:  No!

A:  Not directly in concrete. You could use lead anchors.

A:  No.

A:  I don't know what it's called but it is a square tip bit.

A:  I found this lattice to be very nice to work with, but what I didn't know was how sensitive it was to temperature changes. I secured it snugly like any other project and was told by a contractor to hang it with some looseness or it will crack and break. I was too late. It did in fact break where screws held it. Do yourself a favor, leave the screws a little loose and make the pilot holes a little larger than you would with wood. It does look nice though and is very easy to work with. Just felt a little heads up would have been nice.

A:  Didn't use a bit. Lattice was plastic

A:  Yes, I drilled a pilot hole using 5/64" to vinyl lattice each time I screwed the 1-1/2" lattice to the ledge...

A:  I didn’t even use a pilot hole. Just drilled them in no problem.

A:  I did not drill a pilot hole in the wood, as it was pressure treated pine. The lattice however needs a hole bigger than your screw diameter. I can not remember which size I used.. Do not screw down tight. You want the lattice to hang from your screws so the weather changes will not cause your lattice to contort..

A:  I put screws in corner and installed a screw every 2 feet.on top and sides where possible. My panels wee essentially hung and were in a horizontal configuration. Most of time I had to custom cut the panels to fit ground, which was easy. I used bottom anchors every 2 feet - essentially these were short pieces of 2x2 wood pointed on one end and pounded into the ground. Then I screwed bottom edge of lattice into these 2x2 bottom anchors.

A:  Each panel are framed all 4-sides with 1"x3"x8' S4S Poplar Board. Panel are joined together side by side using 7-screws each joint. I screwed each panel to a 2"x14"x 122 ft long Oakwood using 9 screws on each side (18 total).

A:  7 screws to a post on each side

A:  vertically, I used 3...horizontally, I used 4.

A:  Hello and thank you for your question. You will need 12 total screws, each placed 24 inches apart.
