براغي رأس سداسي 2-4-1/2 × 9 بوصة | فولاذ سبائكي درجة BD عادي | خيط جزئي (1 / عبوة)

Finally got these for assembling a large piece of shop equipment and the alloy steel feels seriously strong—the hex head gives a solid bite with a socket. I've only used one so far, but it threaded in smooth and held tight without any wobble.

I needed a heavy-duty fastener for a machine baseplate, and these grade BD alloy steel cap screws fit perfectly into the hex socket. The partially threaded design made installation straightforward, and they feel solid.

The hex head on these cap screws gripped perfectly with my socket, no stripping at all. I used a few for reassembling a press and the partial threading made alignment much easier. Solid fasteners for heavy shop work.
