Trivd Frol 410 Stainless Steel Self Tapping TEK Screws Assortment,430 pcs #8#10#12 Hex Head Self Drilling Screws for Metal, Length 1/2" to 2"

This set looks solid to me. There are 2 different head sizes, 7mm and 8mm. SAE size will also fit.That’s not a big deal - larger screws typically have larger heads. Some reviewers called this an issue. It’s not.The larger sizes have a clear sealing washer that is removable. The smaller sizes do not have the washer.There is no discussion of the washer in the Amazon description that I could find but there are photos on the web page. See my photos.I used a few of these screws on soft steel, wood and aluminum, no issues. I also used them to attach some stainless steel 2 hole cable clamps to my house, worked great.I would not try to self drill these screws into hard materials like stainless steel or thicker steel. You’re asking for trouble as some reviewers discovered.Stainless screws are hard but brittle and they will snap when used in the wrong materials like stainless steel sheet stock and thicker soft steel.The storage case for this assortment is decent quality, an often overlooked positive feature. I’d rather pay a few extra bucks for a good case.Overall this is great assortment. When used properly these fasteners will work well and thrive in the outdoors.
