M6-1 X 120mm 육각 헤드 캡 나사 | 클래스 8.8 강철 일반 | 부분 나사산 (100개/팩)

The partially threaded design made these perfect for attaching a steel bracket to a frame where I needed the threads to start cleanly. They tightened down with no wobble or stripping, exactly what I needed for a reliable assembly.

Used these to mount a motor to a heavy steel bracket, and the 8.8 grade steel held up perfectly without any stripping. The hex heads seated nicely with a standard wrench, and the partial threading gave just enough grip for the joint. Exactly what I needed for industrial assembly work.

These M6-1 x 120mm bolts are exactly what I needed for a heavy equipment jig; the class 8.8 steel feels seriously solid and the partial threading let me clamp two steel plates tight without bottoming out the threads. The hex heads grab a socket perfectly, no stripping even at good torque.
