براغي تثبيت مقبس نقطة كوب M6 X 50mm | فولاذ مقاوم للصدأ 316 (100 / عبوة)

These set screws tightened down firmly without stripping the hex socket, and the 316 stainless steel gives me real peace of mind in a marine environment. The 50mm length was perfect for aligning some heavy brackets where a shorter screw would have been useless.

I needed a corrosion-resistant fastener for a marine railing project, and these 316 stainless steel set screws fit the bill perfectly. The cup point tip provides a secure, vibration-resistant grip without damaging the shaft. Installation was straightforward with a standard hex key.

Installed these in a marine railing and the 316 stainless is already holding up better than my old zinc ones. The hex socket drive made it easy to torque them down in a tight corner.
