M22-2.5 x 130mm 內六角螺絲 | 六角驅動 | 部分螺紋 | 12.9級合金鋼鍍鋅 (10個/包)

The thread engagement on these M22 screws feels precise, and the zinc plating gives them a clean, uniform look that’s held up well in my assembly work. They’re beefy at 130mm and the hex socket drives snugly without any wobble.

Installed these in a heavy jig fixture yesterday and the partial threads grabbed perfectly without stripping. The zinc plating looks consistent and durable, and the 12.9 grade gives me confidence for high-torque applications.

These held my jig together perfectly on a heavy machining job. The 12.9 alloy steel definitely feels solid, and the zinc plating made them slide in clean without any binding. Nice that they’re partially threaded too, gave me just the grip I needed.
