براغي رأس سداسي M6-1 X 16mm | فئة 8.8 فولاذ أصفر زنك | ملولبة بالكامل (500/عبوة)

Was worried that a 500-count box of M6-1 screws would be full of burrs, but the hex heads are cleanly formed and the threads are sharp all the way down. Class 8.8 hardness is evident—they snugged into my equipment frame without stripping or deforming. These'll last me through plenty of builds.

These M6 bolts are perfect for my equipment rebuilds; the hex heads fit a standard wrench without any slipping. They're fully threaded, which made aligning the mounting bracket much easier. Very happy with the quality for the price.

The yellow zinc finish looks sharp on these, and the threads are clean enough that they seat perfectly with a socket wrench. I used them to bolt down a motor mount, and the 8.8 steel feels solid with no stripping.
