براغي رأس مقبس بنقطة كوب M6 X 20mm | فولاذ مقاوم للصدأ 316 (250 / عبوة)

The hex socket drive made snugging these into a tight coupling a breeze, even with a ball-end wrench. The 316 steel feels properly corrosion-resistant for the salty air out here, so I'm confident they'll outlast the cheaper alloy ones I've used before.

Installed these on a marine railing that gets constant salt spray — the 316 stainless is holding up perfectly so far with no rust. The hex socket drive made it easy to tighten them down in a tight corner where a regular screwdriver wouldn't fit.

These set screws are exactly what I needed for a marine railing repair. The 316 stainless steel feels solid and the hex drive made installation in a tight corner much easier. Glad I bought the 250 pack so I have spares.
