M14-2 X 100mm 六角頭螺絲 | 10.9級鋼 鍍鋅 | 半牙 (25入)

I needed partially threaded bolts for a custom jig, and these M14s fit perfectly with the hex head making tightening a breeze. The zinc plating looks clean and should resist rust well in my shop.

Used these to bolt down a heavy press at the shop, and the partial threading made alignment much easier than fully threaded bolts. No stripped heads or corrosion after a week in a damp environment—solid hold.

The threads are clean with no burrs, so they start easily even in tight holes, and the zinc plating looks uniform across all 25 pieces. These class 10.9 bolts feel solid enough for the heavy equipment frame I'm rebuilding, and the partially threaded length gives good grip without bottoming out.
