M8-1.25 X 12mm 육각 머리 나사 | 8.8급 강철 아연 도금 | 전체 나사산 (300 / 팩)

The hex heads bit down cleanly with a 13mm socket, no slipping or rounding on the first tighten. For a box of 300, every single one had threads cut sharp and the zinc coat was uniform. Got my whole frame bolted up in an afternoon without a single dud.

Zinc plating looks even and clean across all 300, so no rust worries on these class 8.8 bolts. The full threading grabbed nicely in my steel brackets, and the hex heads drove smoothly with a standard wrench.

Needed exactly 12mm bolts for a tight bracket clearance, and these fully threaded hex heads fit perfectly without any extra length to trim. The zinc plating on all 300 pieces looks clean and consistent, which saved me time sorting through a mixed bin.
