M10 X 10mm 육각 소켓 숄더 나사 | 육각 머리 | 육각 드라이브 | 합금강 (50 / 팩)

The shoulder on these is ground so smooth they slide into my fixture bores without any binding, and the hex socket drives cleanly under torque. All fifty arrived with uniform threading and no burrs, so I’ve already used them as pivot points on two builds without a single issue.

Used a few of these as axle pins in a custom build and the precision-ground shoulder fit perfectly into the bearings with zero play. The hex socket drive made installation straightforward even in tight spaces.

The precision-ground shoulder made these work perfectly as pivot pins in my latest build — zero slop on the bearing surfaces. All 50 arrived clean and the hex drives all seated properly. Socket head means I could get a good grip even in a tight spot.
