براغي رأس سداسية M12-1.75 × 20 مم | فولاذ درجة 10.9 أصفر زنك | كاملة الخيوط (100/عبوة)

Picked up a pack for a heavy machinery repair and the 10.9 steel held up perfectly under torque, no stripping at all. The yellow zinc coating is a nice bonus for preventing rust in the shop. Exactly what I needed for the job.

The hex head sat perfectly flush in my socket wrench, and the yellow zinc coating seems tough enough to resist rust in my shop. These are holding a heavy motor mount solid without any wobble. Exactly the right grip for industrial assembly work.

Used these for a heavy equipment jig at work and the fully threaded design made installation a breeze. The hex head grabbed perfectly with a socket, and all 100 bolts were consistent in thread quality.
