براغي مقبس نقطة كوب M3 × 12 مم | فولاذ مقاوم للصدأ 18/8 (1000 / عبوة)

These set screws are perfect for small jig adjustments on my milling machine; the hex socket drive lets me get the torque right in a cramped spot without stripping the head. The 18/8 stainless feels solid and corrosion-resistant, and the cup point grips well. Glad I bought the 1000-pack—way cheaper

Had to tighten a stubborn grub screw on a jig that kept slipping, and the hex socket drive on these gave me the leverage I needed without stripping. The stainless steel feels solid and hasn't shown any rust after a couple of months in a damp workshop.

My job would grind to a halt without these things, and this batch is solid. The cup point bites down securely without stripping, and the hex sockets haven't rounded out on me once. For a thousand pieces, you can't beat that 18/8 stainless for the price.
