M10 x 80mm 內六角螺絲 | 平頭六角驅動 | 合金鋼 (100顆/包)

The hex socket drive makes tightening these M10 screws so much easier compared to standard bolts, and the flat head sits perfectly flush in my jig. I used them for a custom workbench frame, and all 100 pieces had clean threads without any burrs.

I was a little worried about getting 100 of these for the price, but the hex drive on every single one was clean and the alloy steel feels properly hardened. They threaded into my jig plates without any grit or binding, which is exactly what I need for repeat tear-downs.

The hex socket drive seated cleanly with no stripping even after tightening a full jig assembly down, and the alloy steel feels dense enough to trust under repeated load. Pack of a hundred means I've got spares for the next few projects without reordering.
