حلقات قفل بأسنان خارجية M3 | فولاذ مطلي بالزنك (5000 / عبوة)

These are perfect for when you're torquing down small motors or electronics. The zinc plating is consistent and they don’t leave metal dust in the bag, so the threads stay clean. A 5000-pack means I’m set for a long time.

Finally, a hardware order that actually makes sense. The zinc plating looks even and nothing was bent or scratched, which is rare for bulk fasteners, and they’re perfect for my vibration-prone motor mounts.

Pack of 5,000 was more than I needed, but the zinc plated finish on each M3 washer looks clean and should resist rust well. The steel feels sturdy enough to trust against vibration loosening.
