براغي مقبس M16-2 × 150 مم | محرك مقبس سداسي | خيط جزئي | فولاد سبائكي فئة 12.9 مطلي بالزنك (10/عبوة)

The zinc plating looks factory-smooth, and the hex socket drive grabbed my Allen key with zero wobble on the first try. These M16s are plenty sturdy for my jig setup—no complaints at all.

Got these for a machinery repair I was dreading, but the zinc plating made them slide in perfectly without any binding. The hex drive seated deep and held tight even under torque—no stripping at all.

Used these for a jig in my shop—the hex socket drive made installation a breeze with a standard Allen key. The 12.9 alloy steel feels rock-solid, and the zinc plating looks clean with no burrs on the threads.
