Customer Reviews (4.6 / 5 · 5 reviews)

Brian ★★★★★

Packed these out in my shop for a few panel enclosures, and they drove clean with no stripping. The 5000-count box ensures I won't be running to the hardware store again soon.

Stella ★★★★★

Needed a bulk supply for assembling metal enclosures and these #4-40 screws are exactly what I needed—the zinc plating looks consistent and they drive in smoothly with a standard slotted driver.

Jason H. ★★★★★

Got these for a small electronics repair job and the zinc plating looks consistent across all 5000 pieces. No stripped slots or burrs in the first hundred I've used.
