Overview
The HPI Racing 1/4-28 x 8.5mm Black Pilot Nut is a genuine factory replacement nut that secures the flywheel and clutch assembly to the engine crankshaft on the HPI Firestorm 10T and Savage X. The 1/4-28 imperial thread is the standard for many .15-.21 nitro engines.
A damaged or stretched pilot nut causes flywheel slippage and unsafe operation — fresh OEM nut restores reliable engagement.
