M8-1.25 x 50mm 內六角螺絲 | 低頭六角驅動 | 部分螺紋 | 8.8級合金鋼 (500 / 包)

Installing these in a tight jig setup was surprisingly easy thanks to the low profile head. The hex socket drive grabbed firmly without any stripping, and the Class 8.8 alloy steel feels robust enough for heavy use.

The partial threading is exactly what I needed for my jig builds, gives a solid bite without bottoming out. All 500 pieces came sorted and clean, and the hex drive grabbed snugly on every single one. These are going to last me a good while.

Used these on a jig fixture I’ve been building, and the partially threaded design makes clamping down much easier. The hex socket drive grabbed cleanly, and every one of the 500 came out of the box without any burrs. Solid for the price.
