براغي رأس سداسي ثقيلة 1-1/4-7 × 5 بوصة | فولاذ مقاوم للصدأ 316 | ملولبة جزئيًا (2 / عبوة)

Had to replace some old bolts on a marine lift, and these 316 stainless screws handled the saltwater exposure without a hint of rust. The partially threaded design made installation straightforward and secure. Really solid fasteners for the price.

Used these to mount some heavy equipment on our boat lift and the 316 stainless holds up perfectly in the salt spray. The partial threading made it easy to get the initial alignment right before torquing down.

Installed these on a saltwater dock fitting last week and the partially threaded design made alignment much easier than fully threaded bolts. The 316 stainless has held up perfectly through a couple of storms already with zero corrosion.
