براغي مقبس نقطة كوب M20 × 50 مم | فولاذ سبائكي مطلي بالزنك (25 / عبوة)

The hex socket drive made cinching these down in a tight spot under my lathe way easier than wrestling with a wrench. Cup point bit into the shaft cleanly and held firm through a full day of vibration, no re-tightening needed.

Used a few of these to secure a heavy jig on my milling table, and the hex socket made tightening in a cramped spot much easier. The zinc plating looks clean and I haven't seen any rust after a couple weeks in the shop.

The cup point design on these M20 screws really helped them sit flush against the surface. I used them for a heavy-duty jig where the hex drive was a lifesaver in a cramped space.
