M1.6-0.35 x 6mm 內六角螺絲 | 內六角驅動 | 全螺紋 | 12.9級合金鋼鍍鋅 (400 / 包)

I needed a batch of tiny fasteners for a precision jig I’m building, and these M1.6 screws fit perfectly with no stripped heads. The Class 12.9 alloy steel feels rock solid for their size, and the zinc plating looks clean.

These tiny 1.6mm screws are perfect for my small jig project, and the hex socket drive made them easy to tighten without stripping. The zinc plating seems solid so far, no rust even after a few weeks in my damp garage.

I was pleasantly surprised by how cleanly these tiny screws thread into precision assemblies — the zinc plating gives them a nice, even finish. They hold firm in my jig setup without any wobble, which was exactly what I needed for this project.
