#4-40 × 5/16" براغي آلية | رأس مسطح محزوز | فولاذ عادي (3,900 / عبوة)

The slotted drive on these pan head screws gives a nice, secure grip with a standard flathead screwdriver. I’ve had zero issues with them stripping during installation, which is a relief for such small fasteners. Perfect for indoor projects where you need a lot of sturdy #4-40 screws.

Picked up a pack of these #4-40 screws for a small jig I was building, and they fit perfectly in the pre-tapped holes. The slotted drive is old-school but works fine with a standard screwdriver, no cam-out issues.

Was looking for plain steel pan head slotted screws to match a vintage project, and these #4-40 x 5/16" specimens fit perfectly. The 3,900-count package is definitely enough to last a few years of tinkering.
