This light weight wrench is CNC machined to have exact fit over 4mm turnbuckle adjustment nut like ones found on most popular short course truck and on-road touring cars, and the 5mm turnbukle adjustment nut on the T-Maxx, E-Maxx and Revo, and any 1/8th buggy using the 5mm size turnbuckle. Great tool to have for tuning your favorite R/C racing machine.

This color matches up perfectly with Tamiya line of TRF tools.
