I needed nails to keep my rain gutters from sagging in several places, and this was the perfect fix! The crucial element is that extra inch of screw at the end, which means I can utilize the same holes where the original nails were, but now the gutter is tight as a drum.

I had some spikes that would work themselves out every year and I'd have to get a ladder out and smack them back in. These fastenmaster threaded spikes fit very tightly to the fascia board and hold the gutter very well and solve the problem of them working out of place.

Screws are a little bigger than nails that I pulled out. That helped secure them at they went into the hole in the gutter and then into the wood on the back side. I didn't replace all the nails, but about every third one which allowed me to go all the way around the house with this one box. Really makes a difference on gutter security.

Great bite, easy install. I replaced all of the gutter nails (about 90) that were pulling out of the fascia boards after this past winter's snow and ice in a couple hours. Sll I needed was a ladder, a channel lock to get a few nails that had a little bite, and my impact driver. Each box came with a recessed square bit, but I had to use my own impact-bit since the bits that shipped with the screws will not work with an impact driver. (I personally think the impact driver makes it easier to avoid over-tightening the screws.)

I have not used these gutter screws yet, but comparing them with screws I got at HD, I find these to be notably different. The principle difference is that the shank of the screw in the thread region is larger, and the outer diameter of the threads is larger than the other screws I have. I value this feature because it is reasoned that the larger diameter will fit tighter where the original hole may have been enlarged by a loosening nail, and the larger screw diameter will have a tighter fit.

If I find this to be otherwise, after I install a few, I will revise this review.

The #3 Robertson / square drive bit is a short 1" long bit. It would be nice to have a 2" bit, with a retention detent in it, so that it would be more compatible with common drivers. With specialized drivers, most capable of impact, magnetic bit holders to hold 1" bits are dated. I suppose that the 1" bit keeps the cost down, but it would be nice to get a longer bit with a retention detent.
