Customer Reviews (4.8 / 5 · 5 reviews)

Christopher ★★★★★

The fillister head on these gives a much cleaner bite than standard flat heads, and the slotted drive is easy to line up with a manual driver. For heavy panel work, having a full box of 2000 means I never run short mid-project. Exactly what I needed for fastening enclosures.

Richard ★★★★★

I bought a full package of these #4-40 x 1/2" screws for securing some metal panels, and the 18/8 stainless steel feels solid and corrosion-resistant. The fillister head gives a clean, flush finish once tightened.

Hazel J. ★★★★★

The slotted drive on these fillister head screws makes them easy to seat without camming out, and the 18/8 stainless finish is clean and consistent across the whole batch. I used them to fasten a control panel enclosure, and they threaded in smoothly without any binding.
