براغي تثبيت بنقطة كأسية ومقبس سداسي 5/16-18 × 2 بوصة | فولاذ سبائكي مطلي بالزنك (100 / عبوة)

I needed some long set screws to secure a pulley on a keyless shaft, and the hex drive made installation in that cramped spot much easier than a slotted screw would have. The zinc coating seems durable, and all 100 pieces arrived without any burrs or damage.

The cup point tip grabbed the wood perfectly without any splitting, and the hex drive made it easy to set them deep with just an Allen wrench. I used these to fasten some heavy-duty shelf brackets into a workbench, and they haven't budged.

Installing these in a tight spot under the dashboard was a breeze thanks to the hex socket drive, and the cup point really digs in to hold firm. The zinc plating gives them a clean, corrosion-resistant finish, too. Exactly what I needed.
