براغي ضبط رأس مقبس بنقطة كوب | 7/16-14 × 2-1/2" | فولاذ سبائكي (100 / عبوة)

Used these to secure a heavy motor mount that kept vibrating loose, and the cup point really digs in. Even with a high-torque hex wrench, the threads engaged smoothly without stripping.

Had to tighten some machine guard brackets in awkward spots, and the hex socket drive made it easy to get full torque even with limited clearance. The cup point bites in nicely and holds firm—no slipping at all.

I used these for a jig fixture at work and the hex socket drive made tightening them into tight spots effortless. The cup point grips like a vise — not a single one has loosened up under vibration.
