براغي تثبيت مقبس M20 × 25 مم برأس أسطواني محدب | سبيكة فولاذية مطلية بالزنك (50 / العبوة)

The cup point bites into the metal shaft perfectly, no slipping at all. These screws feel solid and the zinc coating looks like it’ll hold up well in a damp garage. Exactly what I needed for a heavy machinery adjustment.

Installed these on a milling machine clamp set and the hex socket drive made final adjustments in tight spots much easier. The zinc plating seems consistent across all 50 pieces, no rough edges.

Cup point bit into the steel exactly as it should, and the hex socket made torquing in a cramped spot way easier than I feared. Zinc coating looks even all around, no flaking out of the package.
