براغي ضغط بنقطة كوب محززة 3/4-10 X 1-1/2" | فولاذ سبائكي (50 / عبوة)

After installing these on a milling machine fixture, the hex socket drive made final adjustments much easier than a slotted screw ever would. The knurled cup point really bites into the workpiece and holds tight even under vibration.

I needed some heavy-duty set screws for a stubborn pulley, and these 3/4-10 x 1-1/2" alloy steel ones fit perfectly. The hex socket drive made it easy to really crank them down in a tight spot.

The knurled cup point on these screws really bites into the shaft material, giving me a much more secure hold than smooth-tipped set screws. They thread into the tapped hole smoothly and the alloy steel feels tough enough for my heavy-duty applications.
