M18-2.5 x 150mm 六角頭螺絲 | 8.8級鋼 原色 | 部分螺紋 (80個/包)

These bolts fit perfectly on my hydraulic press build, and the Class 8.8 steel feels solid under torque. The 150mm length with partial threading gave me just the right grip depth.

The partially threaded design on these is exactly what I needed for a jig fixture—the unthreaded shank gives a clean grip surface without any wobble. The hex heads seated nicely in my socket, and the whole box of 80 arrived with zero damaged threads.

I needed a batch of quality M18 bolts for a frame repair, and the partially threaded design made alignment much easier. These grabbed cleanly with a socket and held torque without any galling.
