براغي رأس سداسي M30-3.5 × 90 مم | فئة 10.9 فولاذ زنك أصفر | ملولبة بالكامل (5 / عبوة)

The hex heads on these are machined clean, so my socket grips them without any wobble. Yellow zinc finish looks uniform and the 10.9 steel feels solid for the load. Wrapped up a pump base mount without a single stripped thread.

The zinc coating looks great and the threading is perfectly clean, so my wrenches slipped right on without any binding. These class 10.9 bolts feel solid enough for heavy machinery work, and I appreciate that they came fully threaded for a tight fit.

Used these M30s to bolt down a heavy press base and the yellow zinc finish held up nicely against some shop grime. The hex heads sat flush in a standard socket with zero rounding, and the fully threaded length gave me plenty of bite for a 90mm grip. Solid buy for the price.
