M8-1.25 x 50mm 소켓 캡 나사 | 낮은 머리 육각 드라이브 | 부분 나사산 | 클래스 8.8 합금강 (500 / 팩)

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.
