5/8-11 X 1-1/2" براغي ضبط بنقطة كوب | فولاذ سبائكي مطلي بالزنك (50 / عبوة)

The hex socket drive made installation a breeze even in that cramped corner of the assembly. These cup points really bite into the shaft without stripping, and the zinc coating has held up well against a little moisture so far.

The hex socket drive made these easy to tighten in the cramped space inside my machine base, and the cup point grabbed the shaft firmly. After a week of heavy use, none have loosened up at all.

I needed a really solid hold for a heavy guard plate, and the cup point on these screws digs in perfectly without slipping. The zinc plating looks consistent and clean, which is a nice bonus for a functional fastener. Installed four so far with zero issues.
