Arrowmax AM-111140 4.0mm Hex Tip Replacement 120mm  [AM-111140]

High-Strength 4.0mm Allen Tip

The Arrowmax AM-111140 is a 4.0 x 120mm Allen wrench tip crafted from spring steel to resist deformation under torque. It is ideal for model builders who need a durable bit that keeps its fit over many service sessions. The precision machining ensures a snug interface with hex screws used across RC models.

Spring Steel Build for Durability

Spring steel provides a balance of toughness and slight flex, which helps maintain contact with fastener faces while reducing the chance of rounding. The extra length on this tip makes it easier to reach recessed screws in tightly packed electronics bays and chassis layouts.

Practical Uses in Model Work

Designed for general RC maintenance, this tip is suited to tasks like suspension tweaks, servo mount adjustments and motor fastenings. It gives you the control to tighten small bolts accurately without slipping.
