براغي رأس سداسية M33-3.5 × 160 مم | فئة 10.9 فولاذ عادي | جزئية الخيوط (15 / عبوة)

Needed a proper set of bolts for a heavy machinery alignment job, and the partially threaded design made installation much easier than fully threaded options. The hex heads held up well under high torque without any stripping.

The hex head on these M33 bolts gives a nice solid grip with a socket wrench, and the 10.9 steel feels tough enough for my heavy equipment assembly. Took a bit of muscle to drive them in, but they held torque perfectly.

I’ve been using these partially threaded screws for heavy equipment assembly, and the hex head drive gives a much better grip than I expected. They drive straight without wobbling, even with a high-torque wrench. Just solid, no-fuss hardware for the price.
