براغي آلة مقصوصة #4-40 × 3/8 بوصة | محرك فيليبس برأس مسطح | فولاذ مقاوم للصدأ 18/8 (600 / عبوة)

I needed some stainless flat heads for a tight spot, and the undercut design on these #4-40s let me get a clean, flush fit where standard screws bottomed out. The 18/8 material feels solid and corrosion-resistant, perfect for a panel I’m mounting outdoors.

The Phillips drive on these #4-40s bites clean every time, and the undercut heads sit flush in my panel mounts without any wobble. I used about half the box on an enclosure rebuild and not one stripped or snapped. Solid stainless steel at this price is hard to beat.

Finally, a small screw that doesn't strip out on the first turn. The undercut on these #4-40 flat heads gives me just enough clearance for my sheet metal joints, and the 600 count means I won't run out mid-project.
