MTX-5 Engine Mount Nut - Arrowmax AM-MTX-H0704 Spring Steel for Mugen  [AM-MTX-H0704]

Replacement nut for MTX-5 applications

The Arrowmax AM-MTX-H0704 is an aftermarket engine nut sized for Mugen MTX-5 style installations, manufactured from spring steel so it keeps clamping force under vibration. It is intended to secure nitro engines to the chassis flange and should be treated as an accessory rather than an OEM part.

Fit notes: this component fits MTX-5 style engine mounts where a mating nut is used and is designed to pair with compatible Mugen Seiki threaded fittings. Before fitting, confirm the thread size and the seating face on both engine and chassis to ensure correct engagement.

Mounting and tuning: align the engine flange and advance the nut to obtain a firm preload, then lock to your normal engine mounting standard. The spring steel body is helpful for holding clamping through heat and vibration, supporting consistent engine position while tuning and running.
