M3 Heat Set Inserts - 5mm OD x 6mm lg, 10 Pack
These brass heat set inserts are the same ones we install in our Modular Flycores! They're slightly longer than the ones spec'd for the Traceur, but we've found they work just fine on our personal builds.
Specs:
OD: 5mm
Thread: M3x0.5
Length: 6mm
Quantity/pack: 10 pieces
