M10 X 120mm 套件肩螺絲 | 套件頭 | 套件驅動 | 合金鋼 (25入/包)

The ground shoulder on these screws is surprisingly smooth, making them perfect for the axle on my latest assembly project. They fit perfectly into the bearing without any wobble, and the hex drive was easy to torque down.

Used one as a pivot for a custom jig and the precision-ground shoulder made alignment much easier than with standard bolts. The hex socket drive also allowed for a snug fit without stripping.

The 120mm length was spot on for my custom printing press roller axle, and the precision ground shoulder made alignment effortless. The hex socket drive seated my allen wrench securely without any wobble. These screws feel solid and high quality for the price.
