مسامير كتف ذات رأس مقبس M10 × 50 مم | رأس مقبس | محرك مقبس | فولاذ سبائكي (25 / عبوة)

The precision-ground shoulder on these made aligning them as bearing axles effortless—zero wobble once torqued down. The hex socket drive bit cleanly and the alloy steel feels solid enough for repeated load cycles.

I needed these for a small robotics project where the shoulder acts as a bearing surface, and the hex socket drive made installation much easier than a standard bolt.

The precision-ground shoulder on these made aligning them for a custom jig axle much smoother than I expected. They’re definitely a solid upgrade over generic bolts when you need a true bearing surface.
