براغي تثبيت برأس كوبية M5 × 20 مم | فولاذ مقاوم للصدأ 316 (250 قطعة/عبوة)

The hex socket drive let me tighten these into a tight bracket without stripping, and the 316 stainless feels much more corrosion-resistant than standard hardware.

These feel really solid in hand, and the hex socket drive bit with a hex key without any wobble. I used them for a small outdoor railing repair, and the 316 stainless is already proving to be rust-resistant after a few days of rain.

Finally a set screw that doesn't strip when I'm tightening it in a tight spot—the hex socket drive bites perfectly every time. For the price, getting 250 in 316 stainless feels like a steal for my marine projects.
