M8-1 X 20mm 內六角螺絲 | 內六角驅動 | 全螺紋 | 12.9級合金鋼鍍鋅 (200個/包)

I needed fasteners for a jig I was building, and these M8-1 x 20mm socket cap screws threaded in smoothly without any binding. The hex socket drive bit fit perfectly, and the 200 count will last me through several projects.

The zinc plating is holding up way better than the cheap bolts I've used before, no rust after a month on my tooling fixtures. Threads cut cleanly into tapped holes without any binding, and the hex socket drive fits standard Allen keys perfectly.

I've been using these for jig assembly and the hex drive makes them easy to work with in tight spots. The zinc coating seems durable and they thread smoothly into tapped holes.
