M18-2.5 x 45mm 外六角螺絲 | 10.9級鋼鍍鋅 | 全螺紋 (150 / 包)

Finally a pack of M18 hex bolts that are actually fully threaded all the way to the head – these class 10.9s held up perfectly when I was assembling a heavy press. The zinc plating is a nice touch, no corrosion worries even after a couple weeks on the shop floor.

The hex heads let me torque these down properly with a socket wrench, which was exactly what I needed for a recent machine repair. The zinc plating looks clean and they threaded smoothly into the tapped holes without any binding.

Installed these on a heavy equipment jig and every single one seated cleanly with no cam-out. The 45mm length was exactly what I needed for the bracket thickness.
