M18-2.5 X 130mm 六角頭螺絲 | 10.9級鋼 無處理 | 部分螺紋 (20個/包)

Used these on heavy equipment assembly and the 10.9 grade handles torque without stripping, which was my main concern. Thread engagement on the partially threaded shaft worked well for thick flanges.

These bolts were perfect for a large assembly jig I'm building; the 10.9 rating gives me real confidence in their strength under load. The partial thread made alignment much easier than dealing with fully threaded rods.

The hex head on these screws is a perfect fit for my socket set, making assembly of the heavy-duty machine frame much easier. The partially threaded design helped achieve a tight, secure hold where I needed it most.
