螺栓，六角頭 M8x25，等級 10.9

These are my go-to for bench work now, the hex head fits a standard wrench perfectly without any wobble. The 10.9 grade gives me confidence they won't strip out under heavy clamping pressure.

The hex head gripped my socket wrench without any slipping, and the 10.9 grade gives me confidence it won't shear under load. Threads seated cleanly into my tapped holes, no binding or debris. These are my new go-to for jig assembly.

The M8x25 sizing was exactly what I needed for securing a jig on my drill press table. These Grade 10.9 bolts feel solid and the hex head fits a standard wrench perfectly without any stripping.
