The Tamiya 15493 2mm Aluminum Lock Nuts include a nylon ring to hold fasteners in place and resist loosening from vibration. They suit common Mini 4WD screw dimensions and small assembly points.
Adding lock nuts can reduce the need for mid-race checks by helping wheels and accessories remain secure. They are a simple reliability upgrade for club racing and casual track use.
The red anodised coating offers a tidy styling touch to Mini 4WD cars and pairs well with alloy parts and painted bodies without adding bulk.
