Eva ★★★★★

Wasn't sure about buying a full box of 600, but the 18/8 stainless is noticeably heavier and more solid than the cheap zinc ones I've used before. The fillister heads seat nicely in counterbores, and they've held up fine through a few washdowns already.

Amelia ★★★★★

These little #4-40 fillister head screws are perfect for a tight spot where a pan head just won't fit. The 18/8 stainless steel feels solid and the slotted drive bit into the aluminum without stripping. Clean finish for a clean repair job.

Harper ★★★★★

Finally got around to using these on a small electronics enclosure where corrosion resistance matters. The slotted drive took a bit more care than Phillips, but the 18/8 stainless finish is exactly what I needed for occasional damp conditions.
