براغي ضبط رأس كوب M12 × 20 مم | فولاذ سبائكي مطلي بالزنك (100/عبوة)

Installed these set screws on a conveyor roller and the hex socket made tightening them in a cramped spot much easier than I expected. The zinc plating seems consistent across all 100 pieces too.

The cup point bites into the shaft firmly before I even get to full torque, and the zinc plating held up fine against my oily fingers. 100 per pack means I've got spares for the next three projects, which is exactly what I needed.

The hex socket drive made torquing these into my machine frame surprisingly easy, even in the tight spot behind the bracket. The zinc plating looks uniform and hasn’t chipped during installation, which is a good sign for long-term rust resistance.
