Customer Reviews (4.6 / 5 · 5 reviews)

Julian ★★★★★

Packed exactly 5,000 screws in the box as listed, which is a nice surprise for bulk buyers like me. The zinc yellow finish held up well during assembly, no flaking or jamming issues.

Stella ★★★★★

Used a few hundred of these on a metal chassis assembly and they cut threads cleanly without any binding. The zinc yellow finish held up well against minor scuffs during installation.

George K. ★★★★★

Finally got these for a small robotics project and the self-tapping tip really grabs nicely in thin sheet metal. The zinc yellow coating looks consistent across all 5,000 pieces, which is impressive for that quantity.
