A-M Gutter Guard - 1/2" #8 Stainless Steel Zip Screws - Self-Piercing Xtra Sharp Tip - Mill Finish - 1/4" Hex Washer Head –100 Pack-Includes 1/4" Magnetic Hex Driver – for Gutter Install

Worked perfectly for installing gutter covers.

Product as advertised. Neatly packed & delivered on time

Screws work great. Comes with bit which is nice. Definitely want self drilling screws for gutter guard install. Without them you need lots of leverage to push screws through aluminum. Ran out and had to buy non self drilling at ACE. Much more frustrating. Worth the extra cost compared to China made junk. Buy extra and return if you don’t need them.

These gutter guards are very easy to install. They snapped right in on my 5-inch gutters. They cut easily with snips. They have a built-in notch so when you assemble them from the left to the right they align properly and perfectly. It is very nice to by a product made in the US of A and have the same quality in every piece. I do recommend that you purchase these with the galvanized hex screws that include the driver. What I especially like about these is that you cannot see these from the ground. Others have a lip that is visible from the ground, the only issues with those are not all match your current gutter colors. I wish I would have known about these sooner. These are the ones for the DIY in just one step, no need to go back with the custom color you may have on your current gutters.

Bought this product in conjunction with leaf guards for my gutters upon the Amazon recommendation. Unfortunately, there was not enough in the package to finish the job completely. Product is otherwise perfect for the job, just too small of a package. Be careful

Screws - they screw in!

Perfect value for the money. Easy to use. Worked for additional holdding.

These screws cost more than the competitors but when you use them, you won’t hesitate to buy more. Even though they’re stainless steel somehow the head is magnetic and fits great in the included magnetic bit holder. The points are razor sharp, so much better than using a self tapping screw that slides all over the place. Cuts into the aluminum almost instantly -just ordered another pack. Well worth it.

The screws themselves are excellent. Easy to drive without pilot holes and being stainless steel, they should outlast the gutters. So on that basis, I'd give them 5 stars. However, each of the 3 packs of screws I received had less than 100 screws in it. The first (which I returned) had only 50, and then the next two had 94 and 96 screws. I didn't need the full 200 so I wasn't too worried about the 2nd and 3rd packs, but it's something worth double checking.

worked excellent

These are excellent, come with a magnetic socket bit head to attach the zip screw to your impact driver. Easily penetrate the A-M gutter guard and into the eavestrough, just avoid the steel supporting gutter cross brackets.

Worked good, but I had to file down the driver bit that was provided

Seem to work fine and after a winter in a stainless steel exhaust venting for a heater they haven't turned to rust. Hard to find these in a store even a fastener specialty shop. Been satisfied with the purchase.
