M24-3 x 170mm 六角頭螺絲 | 8.8級鋼鍍鋅 | 半牙 (10 / 包)

The partial threads on these are cut clean, so the bolts seated perfectly without any binding when I torqued them into the equipment frame. Class 8.8 rating gives me confidence they’ll hold up under load, and the zinc coating looks even and consistent across all ten pieces.

The zinc plating on these M24 hex heads is holding up perfectly in my shop, no rust after a week of exposure. The partial threading makes seating them in a blind hole way easier than full-thread bolts I've used before.

The threads on these screws are nice and clean, they drive in without any binding issues. Used them to secure a heavy support bracket and the 8.8 steel feels plenty sturdy for the job. Exactly what I needed for the machinery assembly.
