براغي رأس أسطوانية M20-2.5 × 80 مم | محرك سداسي | خيط كامل | فولاذ مقاوم للصدأ 316 (25 / عبوة)

The hex socket seated perfectly on my driver, no wobble or stripping even when torqued down tight on a jig fixture. The 316 stainless finish looks clean and the fully threaded length gave me plenty of grip through a 60mm stack-up.

Used these to replace some rusted bolts on a dock railing, and the 316 stainless is holding up perfectly in the saltwater air. The hex socket drive made installation straightforward with an Allen wrench.

Finally, a 316 stainless screw that doesn't gall or seize in wet tooling; the hex socket drive on these M20-2.5s holds a driver perfectly without stripping. They cut clean threads and cost less than a trip to the hardware store.
