M20-2.5 x 50mm 內六角螺絲 | 六角驅動 | 全螺紋 | 8.8級合金鋼鍍鋅 (25個/包)

The hex socket drive seated perfectly on my torque wrench, and the zinc plating handled a few greasy fingerprints without staining. These are going straight into my tooling rotation for the next project.

Pulled these M20s tight for a jig on my milling table, and the hex socket grabbed perfectly without any stripping. The full threading along the 50mm length made alignment effortless. Solid fit for precision work.

The hex socket drive on these M20 bolts fit my hex key perfectly, no wobble at all. Used them to secure a heavy jig on my mill table and they held tight without stripping. The zinc plating looks clean and should resist rust in my shop.
