M20-2.5 x 70mm 六角頭螺絲 | 8.8級鋼鍍鋅 | 全螺紋 (25顆/包)

Put a thread chaser on these to be safe, but the Class 8.8 steel is solid and the 70mm length grabbed perfectly in my equipment frame. No stripping or deformation under the wrench, exactly what I needed for a heavy assembly job.

Zinc plating looks good and the hex heads fit my wrench perfectly without any slop. Used them to bolt down a heavy press at work, and the class 8.8 rating gave me confidence they'd hold.

The fully threaded design on these M20 bolts made aligning them through thick steel brackets much easier than I expected. The hex heads gave a solid grip with my socket wrench, and the zinc coating seems durable. Exactly what I needed for heavy machinery assembly.
