M10-1.5 X 80mm 內六角螺絲 | 平頭內六角驅動 | 部分螺紋 | 10.9級合金鋼鍍鋅 (50 顆/包)

The hex socket drive on these M10 screws is perfect for my jig setup, allowing a clean flat-head finish. They threaded into the pre-tapped holes smoothly with no binding, and the zinc plating looks like it will resist rust well. For 50 pieces at this price, it's great value for precision assemblies.

I needed a batch of strong, partially threaded bolts for a jig I'm building, and the 80mm length was exactly right. The zinc plating on these M10s looks clean and even, and the hex socket drive held the wrench securely during tightening.

Installed these on a jig fixture at work and the zinc plating held up well against minor abrasion. The partial threading made alignment easier than fully threaded bolts I've used before. For the price per pack, these are solid value for precision assemblies.
