مسامير رأس مقبس بنقطة كوب M12 × 30 مم | فولاذ سبائكي مطلي بالزنك (100 / عبوة)

The hex socket drive made tightening these M12 cup point screws in a cramped engine bracket much easier than using a standard hex key. The zinc plating seems durable so far, and the 100-count pack is great value for ongoing projects.

Perfect fit on my milling machine's table clamps — the cup point bites securely without damaging the surface. Zinc plating looks clean and should resist rust well in the shop.

I was worried about stripping the hex socket on these M12 set screws, but the drive held up perfectly when torquing down. The cup point really digs in firmly on a hard shaft, and the zinc plating looks clean and uniform across all 100 pieces.
