Set of 2 GR5 titanium thread reducers.
These thread reducers serve the same purpose as helicoils, but are much stronger and do not cause galvanic corrosion with aluminum.
Ideal for replacing damaged helicoils on aluminum masts. We strongly recommend gluing them in place.
Length: 20 mm – hole depth must be at least 21 mm
Internal thread M6x1 – External thread M8x1.25
