براغي غطاء مقبس M3-0.5 × 30 مم | محرك سداسي | خيط جزئي | سبيكة فولاذية فئة 8.8 مطلية بالزنك (600 / عبوة)

These screws were a perfect fit for securing a small motor mount on my 3D printer build. The hex socket drive let me apply good torque without stripping, and the 600-count box is excellent value for the price.

Used these for building a custom jig and the partially threaded shaft kept the alignment dead straight. The zinc finish looks consistent across all 600 pieces, no burrs or defects.

The hex socket drive bites perfectly without stripping, and the zinc plating on these M3-0.5 x 30mm screws looks clean and even across all 600 pieces. Worked flawlessly for tightening down a tooling fixture in my CNC mill.
