M20 X 25mm ショルダースクリュー | 六角穴付き | 六角駆動 | 合金鋼 (10本/パック)

The ground shoulder on these M20 screws was perfectly smooth—made for a snug fit in my bearing assembly without any wobble. Installed them as axle pins and they're holding up great under load. Exactly what I needed for this project.

Used them as a pivot for a custom jig and the hex socket drive made installation effortless with an Allen key. The precision-ground shoulder fit perfectly in the bearing, no wobble at all.

The ground shoulder on these M20 screws is dead-on, no wobble when I use them as axle pins. They slide into the bore like they were machined for it, and the hex socket grips tight without stripping.
