1-1/2-6 × 7-1/2" براغي سداسية ثقيلة | فولاذ مقاوم للصدأ 316 | ملولبة جزئيًا (1 / عبوة)

The partially threaded design made it much easier to start threading into an equipment frame without cross-threading. These bolts feel solid and corrosion-resistant, perfect for outdoor machinery repairs.

Used a couple of these to secure a heavy pump mount on a boat trailer, and the 316 stainless is holding up perfectly in the salt air. The partially threaded shaft made alignment a lot easier than I expected for such a long bolt.

Picked up a pack of these for a dock repair project. The 316 stainless is noticeably heavier and more corrosion-resistant than the 304 screws I've used before, and the partial threading made starting them in the pre-drilled holes much easier than expected.
