M10 X 16mm 內六角肩螺絲 | 內六角頭 | 內六角驅動 | 合金鋼 (25 件/包)

I used these as replacement axles for a small mechanical assembly, and the precision-ground shoulder made alignment much easier than I expected. The hex socket drive tightened down securely with no wobble. Solid feel overall.

The ground shoulder slides into bearings with zero wobble, and the hex drive seated perfectly on my torque wrench. Used them as pivot pins on a jig and they haven’t budged after a week of heavy use.

The precision-ground shoulder on these is what sold me, and they fit perfectly as pivot pins in my jig without any wobble. The hex socket drive made install straightforward, and the alloy steel feels solid enough for repeated use.
