M6 X 6mm 肩頭內六角螺絲 | 內六角頭 | 內六角驅動 | 合金鋼 (100/包)

The shoulder on these screws is ground so smoothly they spin freely in my bearing mounts. 100 pieces in the pack means I've got plenty for prototypes and final builds. Exactly what you need when you want a precise axle.

I needed precise pivots for a small mechanical assembly, and these M6 shoulder screws fit the bill perfectly. The precision-ground shoulder is noticeably smooth and consistent across all 100 pieces. They work great as axles for my project.

Finally found shoulder screws that actually work as precise pivot points. The hex socket drive makes them easy to tighten without stripping the head. Perfect for my small assembly jigs.
