Some M3 Roll-in Nuts Are Defective Since 2021 Orders For V2 Kit

We found some issue with the M3 roll-in nuts , some holes are offset, and some can’t fit in Misumi HFS extrusions.

There’s the same issue with almost all supplier’s nuts, including ZFhong’s which is in the source guide. so the one from Aliexpress may also not work.

The offset one looks like this , it will cause your rails are also offset or it will loose after long time using .



If you have this issue, please open a ticket , we will ship the right one by DHL and bear all costs arising therefrom (if have, such as import fee)

Sorry for this issue.
