براغي مقبس نقطة كوب 5/8-11 × 2 بوصة | فولاذ سبيكة مطلي بالزنك (50/عبوة)

I needed these for a heavy machinery repair and the hex socket drive made tightening in a tight spot much easier than I expected. The cup point held securely on the shaft without slipping, even under vibration.

The hex socket drive made seating these in a tight spot a breeze, no stripping or wobble. Cup point bit into the shaft like it should, and all fifty arrived clean and consistent. For the price, these are going to be my go-to for anything needing a solid lock.

Got these set screws for a heavy-duty jig I’m building, and the cup point really digs into the shaft without slipping. The zinc plating seems tough so far, holding up fine against a little moisture.
