Customer Reviews (4.6 / 5 · 5 reviews)

Penelope ★★★★★

These little screws are perfect for tapping into thin metal brackets; the 410 stainless steel feels sturdy and hasn't rusted after a few humid days in the shop. I used them to mount a small panel, and they cut threads cleanly without any binding.

George Z. ★★★★★

The Phillips drive grabs the bit nicely and these #4-40 screws cut clean threads into aluminum without stripping. For small electronics enclosures, this 400-pack will last me years.

Chloe P. ★★★★★

I needed some 410 stainless steel fasteners that wouldn't rust, and the pan heads on these #4-40s sit perfectly flush in my small assembly jig. The Philips drive engages nicely without stripping, even when I'm driving them into pre-drilled holes.
