Customer Reviews (4.2 / 5 · 5 reviews)

Ella ★★★★★

Bought these to secure electronics on a vibration-prone project, and the zinc coating has held up perfectly so far. The M3 size is exactly what I needed for those tight spaces.

Charlotte ★★★★★

Perfect fit for securing small fasteners on my RC car build—the zinc coating feels durable, and the whole pack will last me years. They bite well on the M3 bolts, even with some light vibration.

Miles ★★★★☆

Was a bit surprised by how small M3 washers are in person, but they fit perfectly on my PCB mounting holes. The zinc coating looks consistent and should resist corrosion in my project enclosure.
