Each wheel is 30mm in diameter with a 9mm tire width, and each axle is a 2mm thick, 100mm long round rod. The wheels are black, the axles silver, making it a straightforward parts kit for STEM projects and hobby repairs.\u003c\/p\u003e\u003ch2\u003eWhat do you get in the package?\u003c\/h2\u003e\u003cp\u003eExactly 100 black plastic wheels and 50 silver metal axles. The wheels have a smooth, treadless surface and a center hole sized for pressure-fit mounting on 2mm rods. No additional hardware or instructions are included—just the raw components.\u003c\/p\u003e\u003ch2\u003eWheel and axle dimensions at a glance\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eWheel diameter\u003c\/td\u003e\n\u003ctd\u003e30 mm \/ 1.2 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTire width\u003c\/td\u003e\n\u003ctd\u003e9 mm \/ 0.36 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShaft hole diameter\u003c\/td\u003e\n\u003ctd\u003e1.95 mm (fits 2 mm shafts)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAxle diameter\u003c\/td\u003e\n\u003ctd\u003e2 mm \/ 0.08 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAxle length\u003c\/td\u003e\n\u003ctd\u003e100 mm \/ 3.9 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWheel material\u003c\/td\u003e\n\u003ctd\u003ePlastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAxle material\u003c\/td\u003e\n\u003ctd\u003eMetal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat can you build with these parts?\u003c\/h2\u003e\u003cp\u003eThese components are sized for small-scale DIY models: toy RC cars, mini trucks, boat propellers, helicopter landing gear, or any STEM project that needs rolling wheels and rigid axles. The wheel's shaft hole is intentionally 0.05 mm smaller than the axle, creating a friction fit that holds without glue, though a drop of adhesive can make the connection permanent for higher-torque applications.\u003c\/p\u003e\u003ch2\u003eHow does the wheel fit on the shaft?\u003c\/h2\u003e\u003cp\u003eThe wheel's center hole measures 1.95 mm across, designed to press onto a standard 2 mm rod. This slight interference fit keeps the wheel from slipping during light use. For more demanding builds, such as a fast RC car, you may want to secure the joint with superglue or epoxy.\u003c\/p\u003e\u003ch2\u003eDo the axles come cut to length?\u003c\/h2\u003e\u003cp\u003eThe axles are supplied as straight 100 mm rods. You cut them to the exact length you need using a hobby saw, wire cutter, or a Dremel. They are not threaded, so attachment is purely by press-fit or adhesive.\u003c\/p\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003ch3\u003eWill these wheels work with standard RC car hubs?\u003c\/h3\u003e\u003cp\u003eNo, these are raw plastic wheels without bearings or hex adapters. They are intended for DIY scratch-building where you press the wheel directly onto a rod axle.\u003c\/p\u003e\u003ch3\u003eAre these axles strong enough for a medium-sized RC truck?\u003c\/h3\u003e\u003cp\u003eThe 2 mm metal rods are suitable for lightweight models up to a few hundred grams. For heavier vehicles, consider thicker axles or reinforcing the joint.\u003c\/p\u003e\u003ch3\u003eHow many wheels and axles does this set include?\u003c\/h3\u003e\u003cp\u003e100 wheels and 50 axles – enough for 50 four-wheeled vehicles or 25 six-wheeled ones.\u003c\/p\u003e\u003ch3\u003eCan I use these parts for non-RC projects?\u003c\/h3\u003e\u003cp\u003eAbsolutely. The wheels work as rollers for small carts, pulley wheels, or parts for robotic chassis. The axles can serve as structural supports, hinge pins, or spacer rods.\u003c\/p\u003e","brand":"EUDAX","offers":[{"title":"Default Title","offer_id":58075983708463,"sku":null,"price":25.73,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/4478\/7503\/files\/eudax-30mm-plastic-wheels-2mm-metal-axles-combo---100-wheels-50-axles-for-diy-rc-models-1.jpg?v=1781527722","url":"https:\/\/toysforkid.co.uk\/products\/eudax-30mm-plastic-wheels-2mm-metal-axles-combo-100-wheels-50-axles-for-diy-rc-models","provider":"Toys For Kid","version":"1.0","type":"link"}
