Customer Reviews (4.8 / 5 · 5 reviews)

Andrew ★★★★★

The 18/8 stainless steel feels solid and corrosion-resistant, exactly what I needed for outdoor panel mounts. Slotted drive works smoothly with a standard screwdriver, and the 1400-count box will last me through several projects.

Brian ★★★★★

Needed a batch for repairing an old metal cabinet and these #4-40 screws fit perfectly. The 18/8 stainless feels solid and the slotted drive held the screwdriver well without stripping.

Emma S. ★★★★★

Bought these for a small electronics enclosure project and the 18/8 stainless steel is a relief—no rust worries even in my damp garage. The slotted drive catches the screwdriver cleanly, and with 1400 in the pack I’ll never run out mid-build.
