M16-2 X 280mm 六角頭螺栓 | 10.9 級鋼 無處理 | 部分螺紋 (4 個/包)

Grabbed these for a heavy equipment bracket repair, and the 280mm length was spot-on. The Class 10.9 rating gives me confidence they’ll hold up under stress.

Used these to secure a jig on a fabrication table—the partial threads let the bolt seat deep without binding. The hex head took a socket wrench easily, and the 280mm length was just right for the stack-up. Solid feel for the price.

Perfect fit for the heavy equipment frame I was bolting together. The Class 10.9 rating gives me confidence in the clamping force, and the partial threading made alignment a breeze.
