M12 X 90mm 肩螺絲 | 內六角頭 | 內六角驅動 | 合金鋼 (25 個/包)

Used a couple of these as replacement axles on a jig I built, and the precision-ground shoulder made for a perfect, snug fit in the bearing. They came well-packed and all 25 were clean and free of burrs.

The grind on these shoulders is exactly what I hoped for—smooth enough that my axle spins without any wobble. All 25 pieces arrived clean and properly threaded, no burrs to clean up.

I needed a strong pivot for a heavy-duty gate hinge, and these M12 socket shoulder screws fit the bill perfectly. The hex socket drive made installation a breeze, and the precision-ground shoulder provides a smooth bearing surface.
