M36-4 x 90mm 六角頭螺絲 | 10.9 級鋼 無處理 | 全螺紋 (15 個/包)

Finally got these to replace some worn bolts on a heavy press, and the hex heads fit my impact socket perfectly. The 90mm length was exactly what I needed, and having 15 in the pack means I've got spares.

The Class 10.9 rating is the real deal—these didn't budge when I torqued them down on the press frame. Fully threaded all the way, so I didn't have to hunt for spacers to get the grip I needed. Just wish they came in a bigger box, but fifteen was enough to finish the job.

Fit perfectly on the flange bolts for a large press I was rebuilding, and the hex head gave my impact gun plenty of grip. The ten-point-nine grade metal felt reassuringly tough even before torquing them down.
