براغي تثبيت رأس مقبس نقطة كوب M12 X 35mm | فولاذ مقاوم للصدأ 316 (100 / عبوة)

Finally got around to swapping out some old mild steel set screws on a marine hatch and these 316 stainless ones threaded in smoothly with no galling, which was my main concern. The cup point bit into the shaft nicely and held tight after torquing down.

These cup point screws set flush perfectly on my boat railing, and the 316 stainless steel gives me peace of mind against salt corrosion. The hex drive grabbed firmly without stripping for all 100 pieces.

The hex socket drive made installing these in a tight engine bay a breeze. The 316 stainless feels solid and corrosion-resistant, exactly what I needed for a marine application.
