براغي رأس سداسي M12-1.75 × 30 مم | فئة 10.9 فولاذ أصفر زنك | خيط كامل (100 / عبوة)

Needed exactly 30mm bolts for a jig fixture, and these are spot-on length. The hex heads grabbed perfectly with a socket, no stripping.

Threads are clean and the yellow zinc coating is even across all hundred bolts, no skips or dull spots. I used them to re-secure a jig on the mill and the 10.9 hardness held up without any stretch. Socket drive fits snug, no rounding on the hex head.

Had to replace some worn bolts on an industrial press, and these M12 hex heads fit the wrench perfectly. The yellow zinc finish seems thicker than cheaper packs I've used, so they should hold up better in the shop.
