M5 X 25mm 內六角螺絲 | 低頭六角驅動 | 8.8級合金鋼 (400 / 包)

Used a full box of these on a jig for a production run and every single one seated perfectly without any cross-threading. The hex socket drive makes them fast to install even in tight spots, and the 400 count means I won't be reordering for a while.

The low head profile on these M5 screws let me sink them flush in a jig plate where standard cap screws would have stuck out. All 400 in the bag were cleanly threaded with no burs. Exactly what I needed for precision assembly work.

The hex socket drive seated perfectly with my ball-end driver, and the low head profile cleared the tight clearance on my jig without any filing. All 400 pieces arrived with clean threads and consistent plating, so I’ve already used half of them on a shelving frame.
