Thread is approximately 40% stronger
Top where flights lock on are approximately 30% stronger
Overall strength is enhanced by using polycarbonate resin
It's now easier to tell between locked and spinning... Spinning shafts have a rounded top and Locked shafts have a flat top. Also, the top of the locked shaft is now in a matte finish
Only work with Fit Flights
Total Shaft Length (Not including threads) - 2 5/64" - 53.00mm
Shaft Only Length - 38.5mm
Shaft only length is the distance between the flight and the barrel. It does not include the threads or the push-in area for the flight.
If you install flights onto a Locked style shaft and then onto a Spin style shaft, you may notice the flight is looser than normal and may pop off easier. Avoid this by using separate flights for Locked and Spin shafts.
While the manufactures are using materials that should enhance the strength of their polycarbonate shafts-there is no warranty on either shafts or flights
