The Arrowmax AM-410881-BG is supplied as a 5-piece Allen key set tailored to small RC hex fasteners, with a black-gold finish. The included sizes are .035, .050, .063, .078, and .093, each on a 120mm shaft to reach recessed fixings and constrained mounting points.
These keys are useful for careful jobs such as aligning linkages, setting servo offsets, and securing motor brackets. The 120mm length gives added clearance so you can make adjustments without removing surrounding parts when possible.
A targeted set for modellers and technicians who need smaller fractional Allen sizes with extended reach; stow it in your workshop or pit bag for precise maintenance chores.
