Wensilon（200pcs）#8×1”for Sheet Metal Self-Tapping Screws 410 Stainless Steel Truss Head High-Strength Quick Tapping Screws

Used these to replace the screws that came with a raised garden bed. Wanted something stainless steel and also longer than what they provided. These went in great and make me feel confident that my garden bed will last longer. I also like the appearance of these a lot, clean look

When I bought these, I was a little bit worried that maybe because of them being stainless steel, they might easily fall off my magnetic Phillips head driver bit, which would get very frustrating. But after receiving these screws and using a dozen or so of them to drive screws through stainless steel sheet metal and into aluminum, that has NOT been an issue at all. Contrary to what some people think, not all stainless steels are non-magnetic. Some are, and some aren't. So don't think that being magnetic means that these aren't stainless, because they most certainly ARE. I was also a little bit concerned about whether or not these screws, being made of stainless, would be hard enough and sharp enough to be able to self tap into stainless steel, but to my pleasant surprise they worked exceedingly well. I was drilling into a commercial Manitowoc stainless steel ice machine panel, and these screws did not even hesitate to bite right into the stainless. And sometimes also one of the problems that you can have when you use stainless steel screws is that they can snap off when you drill into something kind of thick. The aluminum that I was drilling into behind the stainless steel was probably about 2-3 mm thick, and I did not have any issues with this at all, so again I was impressed with that result as well. I can't make an honest evaluation about corrosion resistance, since it's only been a week or so, but even the magnetic grades of stainless steel should resist corrosion better than just plain steel screws. If you are going to need screws to resist very corrosive environments like salt water or acidic areas, you will likely need a very high grade of stainless that is softer, non-magnetic, and harder to deal with because it can break easy, dull easy, and doesn't stick to your drill driver. But these are perfect for most outdoor applications where rain and sun are the biggest environmental wear and tear factors. And you can't beat the value either.

They work pretty good. Not ideal for metal studs 20 gauge or thin metal but you can make it work. Pretty satisfied.

The screws screwed great but the bit that comes with it not so much

My purchase arrived on time and packed well for the shipping. Works well on thin, soft metal and digs right in.

I used these to mount my Starlink router and power supply to the bed of my truck with ease and it is still holding up very sturdy. I've driven about 2k miles across Texas (terrible roads and highways) and there is no sign of failure. I'm quite pleased with the product for the price.

Ordered despite some negative reviews. BUT, I had NO PROBLEMS whatsoever using these to attach aluminum sheeting to a steel framed garage door. Hint: Go slow on the drilling. Spinning too fast just dulls the drill point. If the drive bit seems loose in the screwhead, dull the point with a grinder just a tiny bit and it will not "jump" from the screw. Also, ease up on pressure. Just enough to give the drill point some "bite". Very happy for my use and these come in handy for a multitude of jobs.

they work well and they fit well in Phillips slot and drill very well into thick steelExceptional quality
