M8-1.25 x 45mm 內六角螺絲 | 低頭六角驅動 | 部分螺紋 | 8.8級合金鋼 (500個/包)

The low head profile on these M8s is a lifesaver for tight spots on my jigs, and the 8.8 alloy steel feels properly rigid. All 500 came in with clean threads and no burrs, so I didn't have to chase a single one before running them in.

Packed the whole box into my assembly tray and the partially threaded length grabbed perfectly in the fixture block. The hex socket drive seated cleanly on my driver with zero wobble, and the low head profile let me slide the guard rail right over them.

I needed low-head screws for a tight jig assembly, and the 8.8 grade alloy steel feels sturdy enough for repeated clamping. The hex socket drive seated perfectly with no stripping, and the partial threading helped with alignment.
