براغي رأس سداسية M2-0.4 × 20 مم | محرك سداسي | خيط كامل | فولاذ مقاوم للصدأ 316 (400/عبوة)

I replaced some metric bolts on a precision jig with these 316 stainless steel ones, and the hex socket drive made installation a breeze with no stripping. The fully threaded design gave me a solid hold, and they feel much more durable than the crappy zinc-plated stuff I used before.

Was a bit worried about these being too small to handle, but the hex socket drive made them easy to tighten in tight spaces. Threads cut cleanly into the aluminum jig I'm building, and the stainless gives me confidence they won't rust.

I needed 316 stainless for a saltwater project and these M2-0.4 x 20mm screws fit perfectly. The hex socket drive makes installation easier than a slotted head, though the 400-count pack is more than I'll use anytime soon.
