براغي تثبيت مخروطية الرأس 3/4-10 × 1-1/2 بوصة | فولاذ سبائكي (50 / عبوة)

Finally a set screw that doesn't strip out when I’m torquing it down in a tight spot—the hex socket drive grips the Allen key perfectly and that cone point seats deep into the shaft. These 3/4-10s are solid alloy steel, and the 50-pack means I won't be scrambling for a spare mid-job.

I’ve been using these set screws for a heavy machinery alignment job, and the hex socket drive made it easy to tighten them in a cramped spot. The alloy steel feels really sturdy, and the cone point held fast without slipping.

The cone points seated perfectly into the shafts on my mill, and the hex socket drive gave me plenty of torque in a cramped spot. All fifty screws came threaded clean, no burrs or junk in the threads. Exactly what I needed for a heavy-duty fixture job.
