Did the job

great!

This pack comes with 50 screws, each M5 size and 20 mm (about 0.79 inch) long, made from 304 stainless steel. The screws feature a button head and Torx drive (T25 bit included), which provides good grip and helps prevent cam-out when driving into wood or sheet metal. All the screws in the pack look clean and consistent, with no visible defects or rough threads. The full threading is even and the heads are finished smoothly. The included T25 bit fits perfectly in the drive and feels sturdy. Pros: M5 x 20 mm sizing, 304 stainless steel construction Button head with Torx drive for secure installation Even, clean threading Includes a matching T25 bit No defects or rough spots in the batch Cons: None noted on initial inspection SUMMARY These screws are reliable and well made, with a clean finish and a good fit for the included bit. A dependable choice for wood or sheet metal projects.

I love the torx head on these. The bit I have grabs these really well. There's pretty good QC on these screws. I haven't seen any defective ones yet. They function more like sheet metal screws than wood screws, so they take a second or two to start grabbing in softer surfaces, but that's no biggie.

These screws appear to be stainless (mildly magnetic), uncoated, well formed, and consistent quality. The surface quality of the screws is a bit less than the product images suggest but is still very good for the price. While these screws are "self tapping", by nature of coming to a point, they do not have any special features to help them self-drill or cut threads so you'll still need to predrill holes to avoid splits depending on your application.

These are quality screws for a fraction of the price at the name brand screws. The quality seems to be right on par with the others and they even came with an impact bit. I've been using them to mount diamond plate aluminum and they look great and the head doesn't stick up too far. Definitely recommend these for your next project.

This 100-pack M4 x 16mm Button Torx Head Self Tapping Screws are excellent quality at a good price for stainless steel screws. The count was spot on +1 and the supplier includes a bit too. I like the T20 Torx head; Phillips head screws work pretty well but Torx screws are better by far since they can't cam out like a Phillips head. M4 screws are close in size to a standard #8 sheet metal screw so they should be interchangeable for most uses. The pics tell the tale. These are high quality screws at a very good price.
