براغي مقبس سداسي بنقطة كوب | 3/4-10 × 3-1/2 بوصة | فولاذ سبائكي (25 / عبوة)

The hex socket drive made it effortless to crank these into a tight jig I’m building, and the cup point bites really securely. The alloy steel feels solid and durable for the price.

I needed some heavy-duty set screws for a large pulley repair, and the hex socket drive let me really torque them down without stripping. The alloy steel feels rugged, and the 3.5-inch length was perfect for getting deep into the hub.

The cup point on these set screws digs in perfectly, holding my fixture steady under vibration without stripping the shaft. They threaded smoothly into the tapped hole with no binding, and the 3-1/2" length was just right for my application.
