براغي رأس سداسي M30-3.5 × 240 مم | فئة 10.9 فولاذ مطلي بالزنك | ملولبة جزئيًا (10 / عبوة)

The partially threaded shank made it much easier to align the mounting bracket without fighting the threads. These bolts feel incredibly solid for heavy equipment, and the zinc coating looks like it'll hold up fine in my shop.

Used these to bolt down a heavy motor mount, and the partially threaded shaft gave just the grip I needed without any slop. Zinc plating is holding up fine after a week of outdoor exposure, no rust starting. Solid class 10.9 feel for the price.

These were the exact length I needed for bolting down an industrial conveyor – the partial threading made alignment way easier. The hex head grabbed perfectly with a socket, no slipping.
