براغي كتف مقبس M6 × 50 مم | رأس مقبس | محرك مقبس | فولاذ سبائكي (25 / عبوة)

The precision-ground shoulder on these screws made aligning the axle on my 3D printer carriage smooth and effortless. They’re a perfect fit for the M6 bearing I had, and the hex drive tightened cleanly without stripping.

Used one as a pivot for a homemade jig and the hex socket drive made tightening a breeze even in a tight spot. The 50mm length gave just enough reach without flexing, and all 25 arrived clean with no burrs. Solid buy for the price.

The precision-ground shoulder on these is spot on—light years beyond the sloppy tolerances I usually get elsewhere. They slide into a bearing bore without any wobble. Exactly what I needed for a pivot arm, and the hex socket drive made installing them a breeze.
