Customer Reviews (4.8 / 5 · 5 reviews)

Ava T. ★★★★★

These #4-40s are exactly right for the small enclosures I’m always fiddling with, and the binding heads seat flush without stripping. The 18/8 stainless feels solid and hasn’t shown a speck of rust after a few damp weeks. A full 300 in the box means I’m set for a long time.

Emma I. ★★★★★

Finally, a box of #4-40 screws that actually has a consistent thread all the way down the shaft. I used a full hundred of them mounting some thin aluminum panels, and not a single one stripped or bound up. The slotted binding head seated flush and gave a clean, professional look.

Jason ★★★★★

Picked up a pack of these for a small electronics project, and the 18/8 stainless steel finish feels solid and corrosion-resistant. The binding head sits flush against the panel without slipping, which made assembly much smoother than I expected.
