براغي رأس سداسية 2"-4-1/2 × 13" | درجة BD فولاذ سبائكي غير مطلي | خيط جزئي (1 / عبوة)

The threads on these Grade BD bolts are cut clean and started easily into my equipment frame. They definitely feel solid and high-quality for a heavy-duty application. Just what I needed for a critical assembly.

Took a while to find a partially threaded bolt this long that wasn't special order, so the 4-1/2" length with that thread gap was exactly what my jig needed. The hex head grabbed cleanly with a socket, and the alloy steel feels dense and solid in hand. Glad I grabbed a few extras.

Used these to secure the motor mount on an old milling machine and the hex head let the socket grip tight without stripping. The partially threaded shank made alignment easy through the bracket. Solid hold so far with no vibration loosening.
