براغي ضبط ذات رأس كوبي 7/8-9 X 4" | فولاذ سبائكي (10/عبوة)

The cup point bites into the shaft exactly where I set it, and the alloy steel feels tough enough for repeated adjustments. Threading these 4-inchers into a tight bore was surprisingly easy with the hex socket drive, no stripped corners. Exactly what I needed for a stubborn alignment job.

These set screws grabbed tight in a pretty worn-out pulley I was repairing, that cup point really digs in. The hex drive made it easy to get them torqued down properly even with limited swing room.

The hex socket drive made it easy to tighten these in a cramped spot without stripping the head. The 4-inch length was just right for the project I was working on.
