M8-1.25 x 150mm 內六角螺絲 | 平頭內六角驅動 | 部分螺紋 | 等級12.9 合金鋼鍍鋅（100個/包）

I needed partially threaded screws for a jig project, and these M8s worked perfectly—the hex drive bit seated cleanly without cam-out. The zinc plating feels consistent across all 100 pieces, no burrs or rough edges.

Finally installed these on a heavy-duty machining fixture I'm working on—the partial threading made alignment so much easier. The zinc coating looks solid, and the class 12.9 rating gives me confidence they'll hold up under constant clamping force.

I needed longer bolts for a jig I’m building, and the 150mm length with partial threading worked perfectly for clamping layers. The zinc plating seems even and durable, no rough edges out of the box.
