This 4pc set of steel screw pins is intended for wheel hex retention on Axial Racing Yeti XL RC models. The pins are sized to pass through the wheel hex and hub interface and secure the hex against rotation or slippage under typical scale off-road loads.
Installation and servicing are straightforward: align the hex and hub and drive each pin through the mating holes to lock the hex position. During scheduled maintenance inspect pins for bending, cracking or tip deformation and replace any component that shows compromised seating to maintain dependable wheel retention.
In a setup context these pins function as a basic retention element rather than a performance upgrade, and they are normally replaced following impact damage or while performing wheel servicing to restore reliable attachment.
