براغي رأس سداسي M5-0.8 × 40 مم | فولاذ مقاوم للصدأ 316 | ملولبة جزئيًا (300/عبوة)

Used these for a marine railing repair where I knew corrosion would be a problem, and the 316 stainless steel is holding up perfectly after weeks of salt spray. The hex head drives smoothly with a socket on my drill.

The partial threading on these M5 screws made installation into my equipment frame much easier than expected. They feel solid and corrosion-resistant, perfect for outdoor use.

Installed these on a marine hatch I was repairing; the 316 stainless handles the salt spray without a hint of rust. The partially threaded design let me get a solid bite into the aluminum frame.
