براغي تثبيت نقطة كوب M8 X 80mm | سبيكة فولاذ مطلي بالزنك (100/عبوة)

The hex socket drive made torquing these into tight corners a breeze, and the zinc plating looks solid so far. Installed a dozen without stripping a single head. Exactly what I needed for my metal fabrication jig.

The cup point really bites into the shaft when you cinch it down, and the zinc plating has held up fine after a few weeks in a damp garage. The 80mm length gave me plenty of grip on a thicker pulley, and the hex socket made tightening in a cramped spot far easier than a hex head would've been.

These hold tight on a shaft even with some vibration, and the zinc plating has kept them rust-free in my workshop so far. Just the right length for the 80mm depth I needed in my setup.
