Evelyn Z. ★★★★★

Installed a few of these into 16-gauge steel brackets and they seated perfectly with zero distortion. The thread feels clean and the steel finish is consistent across all 100 pieces.

Sophia ★★★★★

I needed a clean way to secure panels without access to the back, and these #4-40 steel fasteners grabbed firmly with zero hassle. The threads engage smoothly, and the whole package of 100 feels like a solid deal for general assembly work.

Timothy ★★★★★

Finally, a #4-40 self-clinching fastener that actually holds tight in thin sheet metal without stripping. The steel construction feels solid, and having 100 in the pack means I won't run out mid-project.
