10-piece Blind Nut M5 Set by O.S. Engine OS79870050 for RC Mounts  [OS79870050]

Practical guide for installing M5 blind nuts

The O.S. Engine OS79870050 blind nut M5 set is supplied in a 10-pack to create captive M5 threads where through access is limited. These blind nuts allow installers to fit a reliable M5-threaded anchor into thin panels, engine mounting points, or modular chassis plates found on scale RC vehicles.

Fit each blind nut by placing it into the prepared hole so the flange contacts the component surface, then tighten an M5 bolt to draw the nut into the mounting. As these are intended for confined locations, confirm hole diameter and panel depth before final assembly to make sure the nut seats correctly and the bolt threads engage smoothly.

For tuning sessions and maintenance, blind nuts make it faster to remove and refit engine mounts or body panels since they maintain a permanent female thread. Always use bolts of suitable length for the material thickness to prevent bottoming out or inadequate engagement.
