M3-0.5 × 30mm براغي غطاء مقبس | رأس مسطح بمحرك سداسي | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (600 / عبوة)

Put a handful in my 3D printer’s bed leveling screws to replace the worn-out brass ones — the hex socket grips perfectly with a 1.5mm driver. The 316 stainless feels much sturdier than expected, and the full threading gives a solid bite into aluminum brackets.

Installed these in a marine-grade jig and the 316 stainless held up perfectly after a week in salt spray. The flat head sits flush without any snagging, which is exactly what I needed.

These screws are perfect for the precision jig I’m building—the hex socket drive makes them easy to tighten without stripping. The 316 stainless steel also feels much more corrosion-resistant than the standard ones I’ve used before.
