براغي تثبيت سداسية بنقطة كوب مخددة 5/8-11 × 1 بوصة | فولاذ سبائكي (50 / عبوة)

The hex socket drive makes these incredibly easy to install even in tight spots. Used them for a jig build and they hold firm without any wobble.

The knurled cup point digs in perfectly, and the hex drive made tightening in a cramped spot way easier than I expected. These 5/8-11 x 1" screws feel solid and held firm on the first try.

These set screws have a nice grip with the knurled cup point, so they hold tight even in my more stubborn applications. The alloy steel feels durable, and the hex drive works well in a cramped spot. Exactly what I needed for a heavy-duty adjustment project.
