M10-1.5 X 80mm 六角頭螺絲 | 強度等級10.9 鋼 無處理 | 部分螺紋 (50個/包)

Finally found partially threaded M10s long enough to sandwich a steel bracket and a rubber bushing; the hex heads grab my 13mm socket perfectly. These 10.9s feel solid, no stripped threads so far even torquing them down with an impact driver.

The 80mm length was exactly what I needed for a heavy machinery bracket, and the partially threaded design made installation much easier. These hex head screws feel solid and the finish is clean.

These bolts worked perfectly for mounting a frame to a concrete floor—the partially threaded design made alignment much easier. The hex head gripped firmly with a socket without any stripping.
