M6-1 x 12mm 육각 머리 볼트 | 클래스 10.9 강재 일반 | 풀 스레드 (600개/팩)

These are exactly what I needed for reassembling the motor mount on my mill. The class 10.9 hardness is reassuring for high-torque applications, and the threads are clean enough to start by hand every time. Having a full box of 600 means I won't run out mid-project.

Used these to replace some worn bolts on an old press, and the class 10.9 steel is noticeably tougher than the originals. The hex drive seated perfectly with no stripping at all.

I needed these for a small bracket repair on a conveyor line, and the Class 10.9 steel holds up well under moderate torque without stripping. The hex head drives smoothly with a standard socket, and the 12mm length gave just the right amount of thread engagement for a thin plate.
