I have been using Kreg products of a few years now and I love everything about them. I find that buying the screws here on Amazon is the best buy. I can no longer find them in Home Depot I do not know why, they have changed their dealers maybe?
I am a bit of a late comer and a female so my knowledge is not that of an expert, but I do make some nice things for my home an I find that having the right screw does help.
I do not know how I could have made such a big and beautiful chicken coop without these products.
I do not know about you but when I am ready to make something I do not want to wait for a delivery so I buy big. I have several of these boxes in my shop just waiting for me.
I like to use mostly the coarse screws I feel they just dig in stronger, some like the fine ones. Don't get me wrong I do have the fine ones it is that they are not my favorite.
You may think, a screw is a screw, maybe, but you would be wrong, these are unique in that the heads have a square hole, that can only be screwed in with square driver.
The head is also larger than the average head because it is meant to be used in conjunction with the Kreg pocket hole jig. That is not to say these cannot be used by themselves I have done that also. The head is attractive on top and does not deter from the look of a piece if it is visible.
