M12-1.75×14mm 內六角螺絲 | 六角驅動 | 全牙 | 12.9級合金鋼鍍鋅 (50個/包)

These M12-1.75 screws were perfect for building a jig in my shop. The 12.9 alloy steel feels really solid, and the hex drive seated cleanly without any cam-out. Pack of 50 is exactly what I needed.

I needed some high-strength fasteners for a tooling fixture, and these M12 alloy steel screws fit perfectly. The zinc plating looks clean and consistent across all 50 pieces, which is important for corrosion resistance.

These bolts are perfect for my jig setup; the hex socket drive makes installation much easier than standard hex heads. The 12.9 alloy steel feels incredibly strong, and the zinc plating gives a clean finish. I'll be ordering more for future tooling projects.
