Abigail U. ★★★★★

The square drive on these #4-40s is a lifesaver—no more stripped pan heads when I'm driving them into tight spots. The trivalent zinc finish looks uniform across the whole 5000-piece lot, and they threaded cleanly into my steel brackets without any binding.

Samuel ★★★★★

I needed a bulk pack of small screws for a project, and the trivalent zinc finish on these looks clean and should resist rust. The square drive seats well without stripping, which is a relief for such tiny fasteners. Very satisfied with this quantity for the price.

Edward ★★★★★

The square drive on these #4-40 screws grabbed the driver bit without any cam-out, which made the whole assembly run much smoother. The trivalent zinc finish also looks uniform across all 5,000 pieces, so I didn't have to sort through any duds.
