M6-1 x 30mm 六角頭螺絲 | 10.9 級鋼黃鋅 | 全螺紋 (250 個/包)

Perfectly uniform thread pitch across all 250 pieces, made quick work of mounting my new motor bracket without any binding. The hex heads grip snugly with a 10mm socket, and the yellow zinc coating gives them a nice, consistent shine under work lights.

The yellow zinc coating is evenly applied and the threads are clean on every single screw in the box, which makes them a pleasure to work with. I've got a full 250 to last me through several projects, and the hex heads fit a standard 10mm socket perfectly.

I used a socket driver on these and the hex head held tight without stripping. The yellow zinc coating looks clean and the full threading made installation easy.
