M10 × 90mm ソケットショルダースクリュー | ソケットヘッド | ソケットドライブ | 合金鋼 (25 / パッケージ)

The shoulder on these is ground so smooth it slid right into my linear rail block without any binding. Used six as axle pins in a jig I'm building, and the fit tolerance feels like it was cut for the bearing.

These screws worked perfectly as bearing axles in my latest jig build. The precision-ground shoulder provides a much smoother rotation than I expected from a standard bolt. Exactly what you need for a pivot point that actually spins freely.

I needed a set of precision pivots for a custom jig, and the ground shoulder on these M10 screws is absolutely dead-on smooth. They fit perfectly into my bearing mounts without any wobble or binding.
