M27-3 x 220mm 外六角螺絲 | 10.9級鋼原色 | 部分螺紋 (15入/包)

Perfect alignment holes in my jig plate with these M27 bolts, the class 10.9 steel really bites down tight without stripping. Using a 41mm socket, these cap screws seat flush and hold heavy machinery together solidly.

The partially threaded design made aligning these in a tight flange assembly way easier than dealing with fully threaded rods. Class 10.9 steel feels solidly machined, and all fifteen arrived with clean threads and no burs.

The hex head on these M27 bolts fit my socket perfectly, and the partial threading made aligning the first few turns much easier than fully threaded screws. I used them to secure a heavy press frame, and the class 10.9 steel feels solid with no sign of stripping.
