This comprehensive assortment includes M3/M4 hex screws (Round/Flat head), set screws, washers, lock nuts, body R-pins, solid pins, E-clips, and even replacement O-rings. It’s the ultimate "toolbox essential" for every RC hobbyist. UNIVERSAL COMPATIBILITY FOR TOP BRANDS： Whether you’re repairing a Traxxas Slash, Axial SCX10, Arrma Typhon, or a Redcat buggy, our precision-engineered sizes fit 1/8, 1/10, 1/16, and 1/24 scale models perfectly. The included 3-size hex wrenches (1.5mm/2.0mm/2.5mm) make on-the-go maintenance effortless. RELIABLE CORROSION RESISTANT FINISH：Each carbon steel screw features a professional black oxide finish for enhanced durability and style. To prevent oxidation, we ship our kits with a light protective oil film. Pro Tip from Rufus: For wet conditions, apply a drop of thread locker or lubricant to maintain long-lasting smooth operation.
