براغي رأس سداسية M30-3.5 × 90 مم | فولاذ مقاوم للصدأ 316 | كامل الخيوط (5/عبوة)

Installed these on a heavy-duty outdoor machine frame and the 316 stainless steel held up perfectly through a week of rain. The hex head gave my socket wrench a solid grip without any stripping.

The fully threaded length made cutting one down for a custom jig a breeze, and the 316 stainless finish hasn't shown a hint of rust after weeks of outdoor exposure. Socket drive seats cleanly too, no stripping at the hex head.

Had to swap out some corroded bolts on marine equipment, and the 316 stainless on these is exactly what was needed. The fully threaded design made alignment a breeze with the M30 die. Solid purchase.
