M24-3×140mm 內六角螺絲 | 平頭內六角驅動 | 部分螺紋 | 12.9級合金鋼鍍鋅 (5個/包)

The hex socket drive seated perfectly on my wrench, no wobble at all, and the zinc plating has a clean, even finish that should hold up fine in the shop. For a class 12.9 fastener, the threading is precise and the partial thread gave me just the right grip for a jig I'm building.

I needed some heavy-duty fasteners for a jig I’m building, and the hex socket drive made installation a breeze with my Allen key. The zinc plating looks clean, and the 12.9 alloy steel feels solid—these should hold up well under stress.

The partially threaded design on these M24-3 screws made aligning them in my jig much easier than I expected. The zinc plating looks clean and feels durable, so they should hold up well in my workshop.
