براغي مقبس نقطة كوب 5/8-18 × 2 بوصة | فولاذ سبائكي (50 / عبوة)

Used one to hold a pulley on a motor shaft and the hex socket drive made it a cinch to torque down in a cramped spot. Cup point bit in nicely and hasn't budged since.

The alloy steel feels really solid, and the cup point grips tightly without stripping the surface. These 5/8-18 set screws threaded in perfectly for a heavy-duty jig I’m building.

Installed these in a heavy-duty fixture where I needed a firm hold that wouldn't slip, and the hex socket drive made tightening them quick even in a tight spot. The alloy steel feels solid and the threads were clean right out of the package.
