براغي تثبيت برأس أسطواني بنقطة كوب M3 × 4 مم | فولاذ مقاوم للصدأ 18/8 (1000 / عبوة)

I needed a bunch of small, reliable screws for a tight-cornered electronics project, and these M3 cup point ones grabbed firmly without stripping. The hex socket drive made it easy to apply exactly the right torque in those cramped spots.

The hex socket drive made torquing these down in a tight corner a breeze, and the cup point grips the shaft like it's welded. A thousand of them for this price is just silly good value.

I needed set screws that wouldn't strip under constant adjustment, and the cup point tip on these 18/8 stainless steel ones bites into the shaft perfectly. They're just the right length for my compact assembly—4mm is spot on.
