10×1.25mm DOUBLE JAM NUT Adapter Kit
This Adapter kit is designed to fit the Saito FG57T, 300TL, 300T-TDL, and the 450R. You will probably need a very short screw for this adapter, usually 3/4" to 1" maximum.
If you are using a Tru-Turn HUB, the back plate for the HUB, which you will use INSTEAD of the big prop washer in the kit, needs a steel washer in the appropriate diameter with a 13.5mm hole to accommodate the propnut.
If you are using a spinner, the spinner back plate needs a 12mm ream to fit the stepped portion of the crankshaft.
