براغي ضبط رأس كوبية M8 × 50 مم | فولاذ سبائكي (100 / عبوة)

Took a chance on these for a jig I'm building and the cup point really bites into the shaft, no slipping even under heavy load. The hex socket made tightening in a cramped spot a breeze.

Installed these on a couple of pulleys where I needed a firm grip and the cup point really bites into the shaft. Each screw threads smoothly without any binding, and the hex drive makes them easy to tighten in awkward spots.

Needed a set of these for a machine jig I’m building, and the hex socket drive made tightening them in tight spots a breeze. The cup point really bites into the material, so they hold fast even under vibration.
