براغي رأس سداسي M5-0.8 × 20 مم | فولاذ مقاوم للصدأ 316 | ملولبة بالكامل (300/عبوة)

Installed these for a marine railing repair and the 316 stainless is holding up perfectly against the salt spray. The hex head made driving them into tight spots much easier than a typical Phillips.

I needed a solid batch of M5 fasteners for a marine project, and these fully threaded 20mm hex heads are exactly the right spec—the hex drive on each one grabs cleanly without any stripping.

The 316 stainless is noticeably denser than the cheaper zinc-coated stuff I usually grab, and the fully threaded shank bit into aluminum clean without stripping. Charged through a whole frame assembly with a socket driver and not one of the 300 came out deformed.
