M20-2.5 X 40mm براغي رأس أسطوانية | محرك مقبس سداسي | خيط كامل | فولاذ مقاوم للصدأ 316 (25 / عبوة)

Finally, a 316 stainless bolt that doesn't have me fighting rust on my outdoor jigs. The hex drive fit the Allen key perfectly with zero rounding. These will last years on the dock equipment.

Installing these on a marine equipment repair, the 316 stainless is exactly what I needed for corrosion resistance. The hex socket drive made tightening in tight spaces straightforward, and all 25 threads were clean.

I used these to build a jig for my workshop, and the 316 stainless held up perfectly through a wet grinding session without any rust spots. The fully threaded design gave me plenty of grip for clamping down tight.
