M10-1.25 X 45mm 插座帽螺絲 | 六角插座驅動 | 部分螺紋 | 12.9 級合金鋼 鋅鍍 (50 件/包)

I used these on a custom jig I’m building and the partially threaded design held tight under heavy clamping pressure. The zinc plating looks clean and seems like it’ll resist rust in my shop.

The hex socket drive made these easy to torque down precisely on a jig I'm building, and the zinc plating looks clean. For M10-1.25 x 45mm in a 50-pack, this is exactly what my machinery needed.

The zinc plating on these M10-1.25 screws looks flawless and the hex socket drive bites perfectly with no stripping. I used them to secure a jig for a milling setup and the 12.9 alloy steel feels seriously rigid, zero flex under load. Exactly what I needed for precision work.
