براغي تثبيت سداسية داخلية برأس كوبية 5/8-11 × 2-3/4" | فولاذ سبائكي (50 / عبوة)

The cup point bit into the shaft perfectly on my first try, and the hex socket held steady even when I torqued it down tight. These 5/8-11 screws feel solid and well-made for a fraction of what I'd pay elsewhere.

I needed a heavy-duty set screw for a gear hub repair, and these 5/8-11 cup points grabbed on tight with the hex drive making installation in a cramped spot much easier. The alloy steel feels solid, and the 2 3/4-inch length was just right for my application.

That cup point really bites into the shaft, no slipping at all during setup. I used these on a heavy-duty fixture and the hex drive held solid without stripping. The length was perfect for my application.
