براغي رأس سداسي M12-1.75 × 90 مم | فولاذ درجة 10.9 عادي | ملولبة جزئيًا (30 / عبوة)

The hex head grabbed my socket wrench perfectly, and the 10.9 steel feels rock solid for the equipment frame I bolted together. Threading was smooth, and the partial thread let me cinch down tight without fighting the bolt.

These bolts drove perfectly into tapped holes for a press frame I'm building, and the 10.9 grade gave me real confidence in the joint strength. The partial threading made alignment much easier than dealing with a fully threaded rod in the jig.

Tapped one of these into a stubborn equipment bracket with a 19mm socket and the hex head grabbed perfectly without rounding. The partial threads seated clean right where I needed them to. Solid buy for the price.
