93mm x 3mm Metal Round Rod Bar 30 Pcs for RC Helicopter Model

These get the job done, according to my crappy $20 calipers they are all between 3.00mm - 3.01mm. Surface finish is not the best, but I'm not complaining. For those planning on using these with 623 size radial bearings: 3.00mm shaft is too large. Plan on chucking these up in a drill and sanding them down to 2.98mm... The 20 microns count.

No oily residue. Clean.
