Simple, dependable fasteners make model upkeep quicker and less fiddly. The 3RACING CRA-119 is a compact M4 x 12mm step set screw that secures parts on crawlers without fuss, suited to both bench repairs and outdoor field fixes.
The stepped profile offers a snug engagement in common crawler mounting points so components resist vibration and movement during delicate climbs. It helps keep linkages and brackets sitting where they should while you test line and balance.
Because it suits multiple locations on the Crawler Ex Real series, this screw is useful as a replacement or to carry as a field spare. It is a small, versatile item that can save a recovery or a workshop delay.
