براغي رأس مقبس M20-2.5 × 70 مم | رأس مسطح محرك سداسي | كامل الخيوط | فولاذ مقاوم للصدأ 316 (10 قطع/عبوة)

I needed fully threaded 316 stainless screws for a marine jig, and these M20-2.5 x 70mm fasteners fit perfectly without any corrosion worries. The flat head sits flush against the surface, giving a clean, professional finish.

The hex socket drive seated perfectly with my Allen key, no stripping or wobble during torquing. Threads ran smooth all the way down on my jig assembly, and the 316 stainless finish looks clean against the aluminum. Exactly what I needed for a marine-adjacent setup where rust just isn't an option.

The 316 stainless is the real deal—no rust spots after a week of outdoor use on my jig frame. Threading was smooth all the way down the full length, and the hex socket grabbed cleanly without stripping. Exactly what my precision assembly needed.
