Ella ★★★★★

I needed a bulk supply for small-scale assembly work, and the slot on these #4-40 pan heads is cleanly cut—no burrs to fight with. They thread smoothly into tapped holes without binding, which saves time on the line.

Miles J. ★★★★★

Was worried about the drive slitting, but the pan head held up fine while I was securing a light fixture bracket. Pack of 3,000 means I'll have these #4-40s for years.

Ryan ★★★★★

For a simple indoor project, these plain steel screws did the job without any fuss. The #4-40 threading matched my existing nuts perfectly, and the 5/8" length was ideal for the bracket I was repairing. A whole box of 3,000 means I won't need to restock for a long time.
