Mia ★★★★★

These small #4-40 screws fit perfectly into my model train benchwork where I needed a clean pan head. The slotted drive is easy to work with on delicate parts, and having 4,500 in one package means I won't run out mid-project. Plain steel is just fine for my indoor setups.

Mia G. ★★★★★

These little screws are perfect for the small electronics repairs I do around the house, and the slotted pan head makes them easy to drive in tight spots. At over four thousand in the package, I won't need to restock for years.

Nicholas ★★★★★

Finally found a decent bulk pack of #4-40 screws — these pan heads fit perfectly into my small electronics projects. The slotted drive is old-school but works great with a manual screwdriver for tight spots. Plain steel is fine for indoor use, and 4,500 pieces means I won't run out anytime soon.
