These 3mm titanium flanged lock nuts are made as scale RC replacement hardware for Associated RC 18T platforms. Supplied in a 4pcs pack, they serve as direct-use fastening parts where 3mm threaded fittings are required on the 18T chassis.
The flanged head increases seating area to reduce rotation on alloy hubs and plastic hubs, and the lock feature helps retain clamping during typical off-road bashing and track running. Use conventional hex driver sizes to tighten, and check thread direction and engagement depth when swapping from steel or nylon counterparts.
Installation notes: remove wheel or hub assembly as needed, fit the nut to the 3mm stud, and tighten to a firm hand or light driver torque appropriate for titanium fasteners to avoid over-stressing the stud or hub material. Keep spare nuts in a parts kit for on-track repairs.
