M20×40mm 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 (10個/パッケージ)

I needed a sturdy pivot for a jig I'm building, and these M20 shoulder screws fit the slot perfectly. The precision-ground shoulder makes them spin smoothly without any wobble. Ten in a pack is great value for heavy-duty builds.

The precision-ground shoulder made all the difference when I used these as bearing surfaces in my jig—zero wobble, even under load. The hex socket drive seated cleanly with a standard Allen key, and all ten arrived with clean threads and consistent finish. Exactly what I needed for a solid pivot set

These fit perfectly as a pivot axle in the jig I built, and the hex drive made tightening them down super easy. The precision-ground shoulder really does spin smoothly in the bushing without any wobble.
