براغي رأس سداسي M12-1.75 × 20 مم | فولاذ فئة 10.9 عادي | خيط كامل (100 / عبوة)

Grabbed a pack for a stubborn machine guard that kept vibrating loose, and the fully threaded 10.9 steel really holds its torque. The hex heads sit flush with a socket driver, no stripped edges after a month of daily use.

Packed my fixture plate with these and the hex heads seated cleanly without any cam-out—the Class 10.9 steel definitely feels tougher than the common grade 5 stuff I've used before.

I needed a batch of M12-1.75s for a jig I’m building, and the Class 10.9 steel feels solid under the wrench. The fully threaded length grabbed evenly in the tapped hole, which saved me from having to add washers.
