Cap Screw, M8x25, Socket Head

The hex drive seated snugly on my 6mm Allen key with zero wobble, and the fully threaded shaft made alignment a breeze. Bolted a loose guard back on and it’s held firm through a full day of vibration. Exactly what I needed for the job.

The 25mm length was perfect for reassembling my workshop drill press. The threads ran clean and smooth all the way down.

The hex drive fits my 6mm Allen key perfectly, so no stripping even when I torqued it down. Fully threaded along the whole 25mm, which made seating it in a tight spot a lot easier than I figured. Exactly what the spec said, no surprises.
