براغي رأس سداسي ثقيل 1-1/8-7 × 4 بوصة | فولاذ مقاوم للصدأ 18/8 | خيط جزئي (2/عبوة)

These went on my dock lift and the 18/8 stainless hasn't rusted a bit through a wet spring. The partial threading let me crank them down tight without fighting the whole shank.

Swapped these onto my trailer hitch mount and the 18/8 stainless hasn't shown a speck of rust after a wet winter. The 4" length gives plenty of shank to work with, and the hex head took my impact wrench without rounding.

The threads on these are cut cleanly and the 1-1/8-7 sizing matched my existing bolts perfectly. I used them to bolt down a piece of shop equipment and they torqued down without any galling. Stainless finish looks like it'll hold up outdoors too.
