براغي تثبيت ذات نقطة كأسية M12 × 16mm | فولاذ سبائكي مطلي بالزنك (250/عبوة)

The hex socket drive worked perfectly for tightening bolts in a tight engine bay, and the zinc plating looks clean with no rust after a week. These cup point screws held firm where standard ones stripped out.

Finally a set screw that actually bites into the shaft without rounding off; the cup point on these digs in perfectly. Used them to lock a sprocket on a conveyor line, and they haven't budged after a full shift. The hex socket drive made installation in a cramped spot a breeze.

Grabbed a pack for assembling some heavy-duty shelving, and the hex socket drive made it easy to tighten everything in those tight corners. The zinc plating seems durable, and all 250 screws were clean and consistent.
