براغي تثبيت بنقطة كوب مقاس 3/4-10 × 4 بوصة | فولاذ سبائكي (25 / عبوة)

Installed these on a mill table and the cup point bit firmly into the keyway without slipping. The 4-inch length gave me plenty of reach for a deep adjustment.

These set screws worked great for reaching a threaded adjustment deep inside a machine frame, the hex socket drive made it easy to apply good torque without stripping the head. The cup point tip seated perfectly on the mating part.

Had to swap out a worn set screw on a heavy-duty mower spindle and these 3/4-10 x 4" cup points threaded in perfectly. The heat-treated alloy steel feels tough enough to hold up under constant vibration, and the hex socket drive made cinching it down in that tight spot easy.
