براغي مجموعة رأس كوب M3 X 3mm | فولاذ مقاوم للصدأ 18/8 (1000/عبوة)

Threading them into a tight spot with a hex wrench was surprisingly effortless, and the cup point grips the shaft firmly without stripping. For a thousand pieces of 18/8 stainless at this price, they’re a solid buy for any M3 application I’ve thrown at them.

I've been using these set screws to secure a small CNC jig, and the hex drive makes installation surprisingly easy even in cramped spots. The cup point really bites into the surface, holding tight without stripping. At a thousand pieces in stainless, this pack should last me years.

For such tiny screws, the 18/8 stainless steel feels surprisingly robust and the cup point tip kept them perfectly centered as I tightened them down with a hex key.
