براغي رأس سداسي M6-1 × 70 مم | فولاذ فئة 8.8 مطلي بالزنك الأصفر | جزئي الخيط (200 / عبوة)

The partially threaded design is a lifesaver—it grabs hold right away and pulls the joint tight without any slipping around. These hex heads took a socket wrench cleanly, and the yellow zinc finish looks sharp on the equipment frame.

Used a full row of these m6-1x70s to bolt up a jig frame and the class 8.8 steel took a torque wrench without a single strip. The partial thread gave just enough grip for the locking nut without bottoming out. Solid value for 200 pieces.

Threads cut clean and the yellow zinc finish looks even all the way down, these are solid. I’ve used cheaper hex bolts before, and the Class 8.8 steel here feels noticeably stiffer when I torque them down. The partial threading saved me from having to stack washers on my last machine frame job.
