Yes it comes with tacks in it
I believe these are equipped with concrete nails and I used a 5lb hand sledge hammer to set them. If it is old concrete, you can used a Roto-hammer to pre-drill and attach them with blue Tap-con screws.
The tax strip is about a quarter of an inch thick
because you are buying in bulk.
Yes if the concrete is busted out you can pre-drill and use cut nails or you have to liquid nail it
This particular SKU has only 3 pcs. per pack. However, if you purchase the 1 inch wide tack strips they come 100 to a case.
Thank you for your inquiry. The nail is ¾” long. With the tack strip being ¼” thick, ½” of nail will penetrate into the subfloor.
