Hilitchi 240Pcs 19Sizes SAE Stainless Hex Allen Head Socket Set Screws Grub Screw Bolts Assortment Kit Internal Hex Drive Cup-Point Screws with 7 Hex Wrenches

They seem perfectly fine. Good assortment.

Great

Exactly what I needed. A door knob lost 2 of these grub screws. At the time I didn't have a thread checker so I couldn't tell if it was SAE or Metric. Took a guess and lucked out. Remember to use threadlock if moves frequently.The box is not great for this. The dividers leak and mix if moving the box a lot and you have to keep the piece of foam to seal the lid. Taped the size chart to the lid so I don't lose that. But it's really hard to complain considering the price. Because what else are you going to do, buy them at random?

Arrived on time. Just as described. Met my needs.

This is a good assortment of basic setscrews and the price was reasonable. The shipping was fast as well.

Good quality grub screws, but my box was damaged and the allen wrenches were missing. Not much of a problem for me since I have a large collection of allen wrenches, but still disappointing.

Just the perfect size in stainless for my plumbing project. I needed one (1), now I have 239 left over. Anyone need a set screw?

My antenna uses two set screws and the vibrated out somewhere. I like having different lengths of set screws for different thicknesses of materials. Only thing I found to be lacking is quality of the allen wrenches. Mine stripped out first try on #8 screw.
