براغي ماكينة M3-0.5 × 20 مم | رأس بان فيليبس | ستانلس ستيل 316 (900 / عبوة)

I needed a bulk pack of marine-grade screws for a dock repair, and this box of 900 is a solid deal. The 316 stainless steel feels heavy and non-magnetic, exactly as described.

These screws held up perfectly in a saltwater aquarium sump I built; after three months there's zero rust or pitting. The Phillips drive engaged cleanly without stripping even with a power driver.

I needed some small screws that wouldn’t rust near the saltwater tank, and these 316 stainless ones are working perfectly—no corrosion after a month. The Phillips drive made them easy to seat with a hand driver, and the pan head sits flush on the bracket.
