Losi LOS212051 12mm Wheel Hex Screwpins

This Losi 12mm wheel hex screwpin set is a factory-fit hardware component designed for the Mini LMT monster truck platform. Each screwpin secures the wheel hex to the axle, locking the wheel in place while still allowing it to be removed for maintenance or tire swaps. It replaces lost, bent, or stripped factory screwpins, which are a common casualty of hard impacts, curb strikes, and repeated wheel changes on a hard-driven monster truck. The screwpins are machined to match the Mini LMT's factory 12mm wheel hex dimensions and thread pattern, so they thread directly into the existing hex without needing any other hardware changes. Because they are manufactured to Losi's own specifications, this is a true OEM replacement rather than an aftermarket redesign, keeping wheel retention secure and consistent with how the truck was originally built. The set includes ten screwpins, giving owners enough spares to service every wheel with extras left over for future repairs. This is an inexpensive, essential hardware part for keeping wheels securely fastened and avoiding lost wheels during hard bashing sessions.
