What is included—and not included—in the Stainless Screw Kit?
The model-specific RCScrewZ Stainless Screw Kit includes the stainless screws selected for common assembly locations on ARRMA BIG ROCK 3S BLX 1/10 Electric 4WD MT (ARA4312V3), plus matching nuts and washers where required, extra common sizes, Bondhus short-arm hex wrenches, and a reusable storage case.
