The Tamiya 15454 JR 2mm Cap Screw Kit provides stronger fastenings for Mini 4WD models, improving the assembly integrity of common mounting points. The mixed lengths are intended to swap in for shorter stainless screws where extra clamp is needed, helping to keep assemblies intact during rougher runs.
These cap screws fit standard Mini 4WD and Mini 4WD PRO chassis. The kit supplies 25mm and 30mm length cap screws with matching 2mm nuts and washers. A 1.5mm hex key is included so you can fit and fine tune parts without hunting for tools.
Hobbyists and competitors will find the set useful for preventing screw back-out and maintaining consistent setup under stress. The stronger fastenings reduce the chance of parts shifting and preserve handling across repeated heats.
