Review: Does What Screws Should Do - Bought these for mounting radiators in my PC and attaching parts to 3D prints. They work perfectly for both. The finish looks good and matches my other hardware. None of them stripped, which is really all that matters with screws. The hex heads grip well with my drivers, and the threads cut cleanly into plastic without cracking anything. Shipped fast and the price was reasonable. Not much else to say, they're quality screws that do the job. Would buy again.
Review: A good selection of black oxide M4 button head screws. - The selection is good, exactly as listed. The bolts/screws and their nuts thread on smooth & freely but firmly. The black oxide is satin/rough enough to give that resistance you want, but not crusty or binding. The hardware was all lightly oiled to prevent corrosion. Even the sorting box/container is pretty decent too. Sometimes it's the absolute cheapest/flimsiest box, but this one is firm, and snaps shut securely. The common metric M4 are good for a lot of hobby items, 3D printers etc. Everything includes the Allen wrench these days, but it's nice they included the 2.5mm one anyway. I counted the washers, nuts, and split-lock washers and there were 55 of each as promised. A good value for the money. I'll be getting the M3 or M5 pack from this maker/seller when I need some.
