M12-1.75 X 50mm 套件帽螺絲 | 按鈕頭六角套件驅動 | 全螺紋 | 10.9級合金鋼鋅鍍 (100個/包)

I needed some sturdy fasteners for a precision assembly project, and these M12 button heads fit perfectly with their hex socket drive. The zinc plating gives them a clean look, and the class 10.9 alloy steel feels solid enough for heavy use.

Used them to rebuild a jig at work and the hex socket drive bites perfectly every time, no stripping even at full torque. The zinc plating looks factory-fresh and the thread runs clean on all 100.

Zinc plating on these M12 screws looks solid and consistent across all 100 pieces—no flaking or uneven spots. Used them to bolt down a heavy jig on my mill table, and the hex socket drive made installation smooth even in tight spots.
