M18-1.5 X 55mm 外六角頭螺絲 | 10.9級鋼鍍鋅 | 全螺紋 (25 / 包)

The threading is clean and consistent right to the end, which made installation a breeze. I used these for a heavy-duty jig and they held torque without any stripping. Solid value for a 25-pack.

The hex head on these M18 bolts gripped my socket perfectly, no stripping even torquing them to spec. Class 10.9 steel feels sturdy, and the zinc plating looks clean. Exactly what I needed for heavy machinery assembly.

Used these to bolt down a heavy base plate in my workshop, and the fully threaded shaft made alignment a breeze. The hex head seated cleanly with a socket wrench, and the zinc plating hasn't shown a scratch after a week of hard use. These are solid for the price.
