M10-1.5 x 220mm 六角頭螺絲 | 18/8 不鏽鋼 | 部分螺紋 (20入/包)

The threads are clean and engage smoothly, and the 18/8 stainless finish looks properly corrosion-resistant for outdoor gear I'm bolting together. Wound up using a socket on all six of them, and the hex heads held up without stripping under decent torque. Solid value for a twenty-pack of this size.

The 220mm length is perfect for when you need extra reach, and the 18/8 stainless gives me confidence it won’t rust in our damp workshop. Threads are clean and the hex head grips well with a socket, no surprises.

Used these to fasten some heavy steel brackets to a concrete base, and the partially threaded design made alignment much easier. The hex head gave my socket wrench a solid grip without stripping.
