  • 【Grade 12.9 & 10.9 High-Strength Alloy Steel】Machine screws are manufactured from premium Grade 12.9 and 10.9 alloy steel, offering high tensile strength along with excellent resistance to wear and deformation. M3 Bolts are specifically designed for demanding applications requiring enduring fastening strength and structural stability.
  • 【Black Zinc Plated Corrosion Resistance Finish】Each screw and fastener is coated with a black zinc plating layer to help resist rust and surface corrosion in everyday environments. The uniform black finish also delivers a clean, professional appearance suitable for electronic devices, machinery, and mechanical assemblies.
  • 【Precision Metric Thread & Stable Hex Socket Drive】Accurate M3 metric threading ensures smooth engagement with nuts and tapped holes, reducing installation resistance. The hex socket drive design provides stable torque transfer during tightening, helping reduce stripping and improving fastening reliability in repeated use scenarios.
  • 【Organized Storage for Wide Applications】All 3400 pieces are packed in a labeled storage box for quick identification and easy access. Suitable for 3D printers, RC cars, drones, robotics, electronics repair, furniture assembly, and general workshop maintenance projects.

    I found the replacement parts I needed for my RC truck without having to search through unrelated products. The categories were easy to understand, and the new wheels and suspension parts worked well for my weekend build.

    TinyRacer has a practical selection of RC tools, batteries, and upgrade parts. I picked up several items for maintaining my crawler, and everything made my workbench setup feel much more organized.

    I am still fairly new to RC cars, so I appreciated how clearly the products were grouped. It was easy to compare chargers, connectors, and maintenance supplies for my first off-road vehicle.
