M27-3 x 280mm 六角頭螺絲 | 8.8級鋼 原色 | 半牙 (5 / 包)

Replacing an old coupling on a press line, these M27 hex heads took the full torque without any giveaway on the threads. The partial thread makes alignment a lot less fiddly when the bolt’s long. Pack of five is plenty for a weekend job.

These bolts threaded smoothly into the base plate, and the hex head gave a solid grip with my wrench. The 280mm length was exactly what I needed for a heavy-duty fixture.

Used these to secure a heavy press base to the concrete floor, and the hex head made torquing them down with a socket wrench straightforward. The 280mm length gave just enough thread engagement for our thick mounting plate. Solid hold with no issues so far.
