Customer Reviews (4.8 / 5 · 5 reviews)

Christopher D. ★★★★★

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.

Abigail I. ★★★★★

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.

Alexander ★★★★★

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.
