M10 X 40mm براغي تثبيت سداسية بنقطة كوب | فولاذ مقاوم للصدأ 316 (100 / عبوة)

The cup point on these M10 screws really digs in and holds tight, even in a vibrating application I used them for. The 316 stainless steel feels heavier and more durable than the standard 304 stuff I've tried before, and the hex socket drive made getting them seated flush with the surface a breeze.

I grabbed these for tightening a railing where my socket driver wouldn't fit, and the hex drive held perfectly without stripping. The 316 stainless feels solid and the cup point seats nicely—exactly what I needed.

Needed a reliable set screw for a marine application and these fit perfectly—the 316 stainless is exactly what I was looking for. The cup point grips the shaft firmly, and the hex socket made installation in a tight spot much easier than I expected.
