براغي مقبس نقطة كوب M4 × 35 مم | فولاذ سبائكي مطلي بالزنك (100 / عبوة)

I needed these for a machinery adjustment and the cup point tip really grips well on the shaft. The alloy steel feels sturdy and the zinc plating looks like it’ll resist rust, which is a plus for my workshop.

The hex socket drive made it easy to get these set screws into a tight spot on my 3D printer bed without stripping anything. I used a full package to secure several aluminum extrusions and they've held firm for weeks now.

Had to tighten a handrail bracket in a spot my ratchet wouldn't fit, and the hex socket drive made it easy. The cup point bit into the metal firmly, no slipping at all.
